Dates are a rough estimate, unless actual date is given.  On 2/12/09 I went to the Public Health District and was administered with a Yellow Fever vaccine, Typhoid shot & Hep A (first shot).  The first two were administered into my upper left arm and the Hep A was administered into my right arm or into my buttock region (can not remember). On 2/15/09 I began to feel pain in my upper left arm.  Pain was being treated with regular Tylenol. On 3/??/09 (first week) I went in to see the doctor about getting a tetanus shot and I informed them of the pain in my arm.  They did not think much of it and just continued with my Tylenol pills. ~Early May the pain stopped. ~Mid June the pain came back, but was worse.  The pain felt like a burning sensation within the humerus bone (upper arm). Next month and a half the pain was getting worse. Some time in this period, I saw my primary care provider and was seen by a doctor who ordered an MRI and some nerve testing in my neck, back, and left arm.  Nerve test came back negative, with a possibility a slight carpal tunnel syndrome in my left wrist. On 08/23/09 I went the emergency room, because the pain was so unbearable; I was given pain medicine (shot); started taking Vicodine for the pain. On 08/24/09 Left work early due to the pain (currently this is the last date that I have worked). On 08/24/09 Went again to my primary care provider and was told to take Tramadol HCL On 08/27/09 Went again to my primary care provider because the pain was getting worse and I could not sleep, laying down nor could I find any comfortable position on the couch or recliner and was told to take Hydro/APAP 10/325 tab (2 at a time every 4  6 hrs as needed for pain) Medicines only gave 1/2  1 hrs of relief. Mid September, an MRI revealed that I had three budging disc (C4  C6). On 09/19/09 Went again to my primary care provider because the pain was getting worse and I still could not sleep, laying down nor could I find any comfortable position on the couch or recliner and was told to take Oxycod/APAP 10/325 tab (2 at a time every 4  6 hrs as needed for pain) and also Nortriptylin 25MG (to try to make me drowsy and see if could sleep).  Medicines only gave 1  2 hrs of relief.  ~Late September, Pain continued to get worse pain was now also on the outer side of the left elbow, crossing over the top, moving to the inside portion the forearm, then to the index finger.  The index finger felt like I had slammed my finger (from last knuckle). ~ Late September, received a shot into my C6 disc pain got worse, now the pain was also in the wrist, back of the hand and bottom thumb portion of the palm. ~ Late September, second MRI was ordered for my left shoulder this was to rule out a rotor cuff injury.  Shoulder specialist said that the test came back negative. ~ Early October, third MRI with a dye injection was ordered for my left shoulder this was to rule out a slap lesion.  MRI revealed a slight tear, but the specialist did not think that this was the root of my problem and refused to do any surgery. ~ Mid October, received a shot into my C5 disc did not change anything. On 11-02-09 I saw a Neurosurgeon who diagnosis my condition as "Upper Brachial Plexitis" and he believes that it stems from my immunization shots issued on 02/12/09.
