I did the same thing recently with my elbow. I lifted in my 20s but I got busy with work and family in my 30s and tried to start lifting again at 39 and managed to injure my forearm/elbow. It's damn near impossible to do upper body exercises when you can't grip the bar or dumbell without elbow pain!

It's been like 6 months and it's finally starting to feel better. My cardio is pretty damn good though because while I couldn't lift I threw myself at cardio extra hard.

Can't let the old creep in! Exercise keeps the old out!
