What causes pain in forearm & muscles?
Patient: my left hand starting hurting about an hour ago...near my thumb...now the pain is going up in my forearm...and slowly to the upper arm.... hurts very bad. nothing else seems to hurt...but i can t sleep...as the pain is hurting so bad. the muscles just feel so weak...like my arm is about to fall off. Doctor: Hello,  I would explain that your symptoms could be related to a pinched nerve.   For this reason, I recommend taking ibuprofen for the pain and having some rest.   If your situation does not improve, going to the ER may be needed, for a physical exam and some blood lab tests (a cervical spine X-ray study, complete blood count, PCR, ESR for inflammation).   Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. Ilir Sharka, Cardiologist
