Take a week off from that movement and focus on other things or do one light work set (50% 1 RM). I had tendonitis in my upper shoulder/bicep and it worked for me.
Didn't mean to come across as overly harsh regarding your doc but I and people around me have had bad luck with most GPs. A friend I know broke her foot and the doc literally didn't do anything or prescribe anything other than Ibprofun. No cast, no therapy, no nothing. She had to go to her friend who was a physical therapist to get actual advice and buy a walking boot with her own money. You'd think going to a doc and getting back advice like "yeah that sucks, oh well, now pay me" would be unacceptable but here we are. Same thing with "don't do that thing that makes you hurt anymore".
I get all of my info from a fat Texan anyways.
Here is his podcast talking about docs
In other news I'm about to hit 1300lbs total for my big 3 lifts (Squat, Bench, Deadlift), so that's exciting.
