I had a bit of an accident in the gym which has left me with a slight “compression” of my ulner (sp) nerve in my elbow. My fingers are constantly tingling and my doctor says 4 weeks rest minimum and then maybe an operation. Has anyone ever had this before and what do they recommend? Are there any things I should especially avoid doing in the gym if I do go back anyhow? Or better yet, are there any upper body exercises that are still possible? I dont want to find out the hard way.
