If there s pain in the elbow speciale when i workout triceps pull down or sometimes in sleeping. what can i do, if there any procedures i have to make?

Varies: There are a few potential causes and you may want to be checked. Probably the most common cause is a tendinitis of the triceps tendon. You would want to make sure you warm up well before working out with appropriate stretching and also avoid things that clearly aggravate it. If it does not improve an exam and appropriate studies can determine much more. Thank you.
