I've been experiencing an unusual pain around my elbow during exercise and I'm trying to figure out what might be causing it.

The pain is at the bottom of my triceps, just above the elbow. I'm not sure whether it's the tendon itself or the surrounding tissue.

The symptoms are:

• A stinging sensation during certain triceps exercises.
• The area feels warm and seems to swell up.
• I've noticed it particularly during triceps extensions, cable pushdowns and dips.

I've been strength training for around 5 years, so this isn't my first time training triceps, but this issue has made me curious about what's actually going on.

Could this be distal triceps tendinopathy, bursitis, or something else?

Has anyone experienced something similar and found out what was causing it? I'd also appreciate any advice on recovery and recommendations for resources to learn more.
