Sometime i feel a Sharp pain in the left arm.
Like if someone would stab me with a knife in the arm.
What could cause this?
Pinched nerve. I have one in my upper right side of my back right below the traps. It’s a sharp pain that hits at random and usually always during shrugs. It was real bad for 8 months but is much better now. It’s just swelling of tissue hitting the nerve. Very slow to go away. Eat foods that reduce inflammation. Ice the area where the nerve is being impinged if you can locate it.
Bro have you tried dry needling? really works. Got my imginment out of the way.
