Additional information: Patient reported that when she gave her shot, patient guessed she must had hit a muscle or something but patient woke up the next morning, her arm was all swollen and red, pretty good size. Patient called doctor to find out what to do, she recommended a cream to put on it, took care of the swelling and the fever that was in it. But patient still has a knot underneath where she gave her the shot. Patient has lost a lot of use of my arm she can hardly open up a lid, take a lid off or she cant open up a can with a can opener. Just weird stuff. Wondering if there was anything she can do about this, and if this was going to last forever hitting a muscle like this, that's what the doctor said she probably did. Patient reported she even messed up in other arm when she gave her the pneumonia shot, she had to go and get another vial of whatever it was and go give her another shot because she, patient guessed gave her that shot too high and gave her the booster shot too low. When she saw doctor a couple of weeks ago again she told her her arm was still hurting. Patient still has a knot underneath, where she stuck the needle in, it's a pretty good size know, patient wakes up every morning and has to scratch it but I can't scratch too hard, she can feel it in her arm, it is raised. Patient stated that this thing is not a side effect from the vaccine shot that the person that gave her, the shot administered it the wrong way.  No follow-up attempts are possible. No further information is expected.
