I've been dealing with some horrible tendinitis (I think) in my bow arm elbow for the last couple of weeks.  Pretty sure it's from recently getting back into weight lifting. I just got a new PMA and have been wanting to get it tuned. Shooting today went from mildly uncomfortable at full draw to hardly being able to hold at full draw at all. Anybody with this issue noticed a difference in going to a lower wrist grip? Planning to make a doctors appointment Monday. I've had surgery on both shoulders, so I'm sure it's all related. 

it might be what they call tennis elbow.

Don't know about a PMA but a few years back I went from really heavy Hills to an SAii to add some mass to my overall bow trying to solve what they referred to as "Golfers Elbow"
If I remember right it was a difference of what side of the elbow, inner or outer... mine was inner.
I had assumed mine was from shooting those 100lb+ ASL bows, that had relatively no mass so all the energy was landing in my hand.  Took about 5yrs off from that went down to a 65# widow, and a couple of ILF rigs with a bit more mass, settled into two Hurst bows for the better part of the last 3 years... and just now coming back to a 50/60# Hill in the last couple weeks.  Definitely miss ASL bows

If you're hitting up the doc, they will have some deliberately tests and things. I did a lot of "Nerve Glides" kinda like stretches for your nerves that you aren't suppose to hold. And they had me do some weird rubber twisting negative thing that seemed to help a little bit, with like a 1" diameter foam rubber thing. It's been a total of 8yrs trying to deal with it. that pains gone now but my hand falls asleep a lot and they said they are talking about rerouting my ulnar nerve at my elbow... long run im. It sure if that's a cause or effect. And haven't decided if I want someone cutting into me for something so trivial

Good luck with your docs. Hopefully they are more user friendly than some of mine
