Sore elbow

Lola0ne

I know I could scout around the internet and most likely will have to go to the doctors, but anyone else experience a very painful elbow when doing tricep extentions or bicep curls? It's on the bony outside and only my left. I started lifting again in January, not very heavy but a fair amount of reps and it's just gotten worse. So bad, that today I couldn't lift with my left.
