Clinical course: Since I took 2nd dose of the vaccine, I have been having severe pain in the vaccination location (upper muscle of the left arm). Pain in the vaccination location never goes away. Sometimes the pain spreads all over the left hand and gets worse. Initially, I thought it was regular vaccination pain but with the time it just got worse. I have been seeing my physician since the beginning of the pain but nothing really helped. After treating the pain, my physician said that it's possible that the nurse who gave me the shot probably messed up a nerve. That's why I am having this continuous pain. I am still going to physicians regularly and spending lots of money but nothing is helping. On a scale of 1-10 (10 being the worst), 5 is my pain level all the time. TO make it worse, the pain level sometimes goes up to around 7-8. This pain is bothering me a lot & wasting my money. I can't sleep on my left side nor I can move my left arm comfortably because of this pain. Additional information: Facility type vaccine was school or Student Health Clinic.
