I started working out with free weights a couple months ago and have been making good muscle and strength gains. In the past week and a half I increased a lot of the weight so I could stay within my 6-12 rep range for my upper body which seems to give me a good workout. I've had this issue in my right arm for awhile, but now it's getting a bit worse. When I do pushups I get this tingling sensation in my right elbow, when flexing it hurts a little bit and when I rest that elbow on something it causes my fingers in that arm to get numb for awhile. I've read that it could be a torn tendon of some sort, but I'm not sure.
I've also followed advice of giving yourself 1-2 days of rest in-between workouts to allow your body to heal. I've been doing proper form and have not done anything that I couldn't handle with ease.
Unfortunately a doctor visit isn't an option unless it's something serious since I don't have insurance and I'm already in debt to the doctors office in the $10,000 range.
What could this be?
