I've been having some elbow pain lately. It started a couple of weeks ago when I tried to move up 5 lbs on my overhead press, and it actually felt pretty severe. I did one set of 5 on my top set and felt a sharp pain building in my left elbow. I rested for a couple of minutes, to see if it would go away, attempted another set, and before I could even fully extend the weight, my elbow hurt way too much and I racked the weight. My entire left forearm and including my hand started to tingle, so I stopped pressing movements for 4 days, then tried overhead press again. However, it still hurt mildly despite deloading 10 lbs.
The pain is also there when I do bench press, but not quite as bad, even when I do my heaviest working set.
It's a sharp pain when I'm pressing a weight, and it persists for a short time after exercise as a dull, throbbing pain that seems to radiate from the ulnar portion inside the joint near my bicep. When I flex my bicep, either with my arm extended or contracted, the pain becomes more pronounced. I feel no pain when doing a tricep extension. In upper body pressing movements, and even in the row, the bicep and tricep are acting as stabilizers, and my elbow was slightly aggravated today after doing bent-over rows.
I have tried improving my technique, really paying attention to how experienced powerlifters are pressing and reading about common elbow problems. It's not tennis elbow, golfer's elbow etc. It's not a problem with the ulnar nerve. I don't know what it is. I did find out my forearm hasn't been totally perpendicular in relation to the ground/bar and correcting my grip and elbow movement when I bench pressed did help a little.
I'm sure it matters, but I actually bowled for 10 years from age 5 to 15, and I haven't experienced any pain or discomfort in my right shoulder or right elbow, I think bowling that much while I was young developed the connective tissue in my right arm well.
For the time being I've been doing alternating DB curls in place of overhead press and bench press. Really the only thing I can think to do right now other than seeing some specialist to figure out exactly what the problem is, is developing my biceps because I think the problem is at least partially attributable to a very weak left bicep. I'll do this for maybe 2-3 weeks, then start low on the OHP and bench press and see what happens. I don't believe in taking ibuprofen or anything like that to reduce the pain. If I'm hurting, my body is telling me something is wrong and I don't want to ignore it or make it disappear.
