CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    The instant application is a nonprovisional application of U.S. provisional application No. 61/276,897, filed on Sep. 17, 2009, and entitled “Squeeze-Reliever” inflatable pressurized bladders in housing pain reliever, and it is respectfully requested that this application be accorded the benefit under 35 USC 119(e) of said U.S. provisional application. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to a pain relief apparatus, and more particularly, a device for providing therapeutic pressure therapy to parts of the body for treatment of pain. 
         [0004]    2. Description of the Prior Art 
         [0005]    Numerous innovations for pressure applying devices have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes which they address, however, they differ from the present invention. 
         [0006]    A FIRST EXAMPLE, U.S. Pat. No. 3,581,740, Issued on Jun. 1, 1971, to Sherbourne teaches an inflatable splint for extending the fingers and wrist of the hand of the wearer. The splint has an inflatable chamber extending over the hand and wrist area of the wearer, with one surface which assumes a planar configuration when the splint is inflated. The one surface has finger loops adapted to receive the fingers of the wearer and positioned such that, upon inflation, the fingers will be moved to a normally extended, spaced-apart position. Wrist straps on the wrist area are provided to encircle the wearer&#39;s wrist so that, upon inflation, the wrist joint of the wearer will be moved to a straight position along with the extended fingers. 
         [0007]    A SECOND EXAMPLE, U.S. Pat. No. 3,595,225, Issued on Jul. 27, 1971, to Beeman teaches a support or brace means applicable to portions of a human hand and comprising a twisted, substantially U-shaped, resilient body portion terminating in pressure applying end portions. The end portions apply pressure in substantially opposite directions. The supports of the present invention may be applied to the hand so as to apply substantially oppositely directed pressures to the distal and proximal metacarpal joints of the thumb or first digit, and they may be applied to any of the four remaining digits to exert opposite pressures to adjacent digital bones or phalanges to correct misalignment brought about by arthritis and the like, and to relieve the attendant pain. 
         [0008]    A THIRD EXAMPLE, U.S. Pat. No. 3,654,917, Issued on Apr. 11, 1972, to Dienner teaches an electro-magnetic device having a plurality of movable applicators adapted to be brought into yielding engagement with an affected finger, and vibrated. The applicators, as a group, surround the finger and are pressed against the sides of the finger and are moved lengthwise of the finger back and forth over one or the other of the two free finger joints with a stroking motion. 
         [0009]    A FOURTH EXAMPLE, U.S. Pat. No. 4,182,338, Issued on Jan. 8, 1980, to Stanulis teaches a device which prevents bleeding through needle puncture wounds by applying pressure to the wound through an elastomeric appliance having a blunt skin abutting surface held in place over the wound by securing straps. The pressure applied by the device is sufficient only to prevent bleeding through the wound and does not impede the subsurface flow of blood. 
         [0010]    A FIFTH EXAMPLE, U.S. Pat. No. 5,695,520, Issued on Dec. 9, 1997, to Bruckner et al. teaches a pressure-applying device for relieving distress that includes a pressure applicator having a plate member and a pressure-applying body attached to and protruding from one of a pair of opposite surfaces of the plate member. The plate member has a central portion with a pair of opposite surfaces facing in opposite directions and a peripheral portion surrounding the central portion and having a pair of first opposite sides respectively connected to opposite ends of the central portion and a pair of second opposite sides spaced from a pair of opposite edges of the central portion so as to define respective elongated enclosed slots within the plate member between the second opposite sides of the peripheral portion and the pair of opposite edges of the central portion of the plate member. The device also includes a flexible strap attached to the plate member and adapted for wrapping and securing around a part of the body of a user so that the pressure-applying body is between the flexible strap and part of the body and is in contact with a selected point on the part of the body of the user for applying pressure thereto. 
         [0011]    A SIXTH EXAMPLE, U.S. Pat. No. 5,788,657, Issued on Aug. 4, 1998, to Burns teaches a small hand-held device having a body of electrically insulating material, and a central rod of electrically conductive material which provides for the rod extending beyond a proximal and a distal ends of the body to form electrical contacts. Therefore an electrical conduction path is set-up between the contacts. This path is advantageously used to establish a charge state on the skin surface so as to help in relieving localized pain. A pointed proximal end of the device enables an effective massaging action when the device is brought into contact with the skin and pressed into it. 
         [0012]    A SEVENTH EXAMPLE, U.S. Pat. No. 5,837,004, Issued on Nov. 17, 1998, to Lavore teaches a device to reduce pain, relax muscle spasm, decrease swelling, and increase circulation to the bones, joints, and muscles of the face of a patient having temporomandibular joint dysfunction, the device having a thin, hexagonal configuration with an essentially uniform cross-section, and a flexible outer envelope having a perimeter limited to covering an area on one side of a patient&#39;s face to minimally include the area over the rear portion of the patient&#39;s mandible, the zygomatic arch, the front portion of the temporal bone, the great wing of the sphenoid bone, the lower front portion of the parietal bone, the outer envelope also having hook material on both sides of the upper panel placed away from the patient&#39;s face so that it can also be used inside-out against the opposite side of the patient&#39;s face and the lower rear portion of the frontal bone. Also the outer envelope is secured to the treated area by a separate quick-release non-stretchable strap comprising pile material on one of its sides, and the outer envelope has a removable inner member comprising a gel that can be heated and chilled, without hardening. Applications of the present invention, although not limited to the minimizing of pain, muscle spasms, and inflammation of joints associated with temporomandibular joint dysfunction are best suited for such purposes since its perimeter closely approximates the area on a patient&#39;s face which contains pain sensitive structures most commonly affected by temporomandibular joint dysfunction. 
         [0013]    It is apparent now that numerous innovations for pressure applying devices have been provided in the prior art that are adequate for various purposes. Furthermore, even though these innovations may be suitable for the specific individual purposes which they address, however, they would not be suitable for the purposes of the present invention as heretofore described. 
       SUMMARY OF THE INVENTION 
       [0014]    AN OBJECT of the present invention is to provide a device for providing therapeutic pressure therapy to parts of the body for treatment of pain that avoids the disadvantages of the prior art. 
         [0015]    ANOTHER OBJECT of the present invention is to provide a device for providing therapeutic pressure therapy to parts of the body for treatment of pain that is simple and inexpensive to manufacture. 
         [0016]    STILL ANOTHER OBJECT of the present invention is to provide a device for providing therapeutic pressure therapy to parts of the body for treatment of pain that is simple to use. 
         [0017]    BRIEFLY STATED, STILL YET ANOTHER OBJECT of the present invention is to provide a device for providing therapeutic pressure therapy to parts of the body for treatment of pain which comprises a housing assembly having a front opening to receive the part of the body therein. A first pneumatic bladder is in the housing assembly at bottom of the front opening.
