my experience with the many injuries ive had is to make sure you dont do anything at all that agitates it in the gym, and the things that dont aggravate it, take it easy, cut your poundages in half, dont go to failure and train like a complete girl until that area feels new again
masking it with gear or anti inflammatory's will prolong the injury, thats my experience of it anyway
I agree, with the exception of tendinitis. Tendinitis is one if those things where it is detrimental if you immediately cease all aggravating movements. With tendinitis, you've got to lower the load, but keep reps going, bringing blood and nutrients to the musculotendinous unit. Tendinitis is a bitch but youve gotta work through the pain.
