I'm dealing with this consistent pain running from the back of my left shoulder to my hand, and it's been like this for a month now. I started with severe pain and had to take an injection from an orthopedic doctor. I also went through physiotherapy with heat and IFT for a week. The physiotherapist mentioned I have a muscle spasm, but my orthopedic doctor thinks it might be Fibromygenia. I'm doing exercises every day, but the pain in my left hand gets worse as the day goes on. What do you think is going on? Any advice would be really helpful.
