Seeking Advice on Musician Injury

Thought I'd try here to tap the knowledge of all the musicians in the community.

A family member who is an orchestral percussionist has been suffering for 1.5 years with an overuse injury in both arms, wrist to elbow. He's seen a physiatrist, orthopedist, rheumatologist, and neurologist.  Numerous blood lab tests. Two courses of prednisone and a long course of meloxicam (anti-inflammatory). He's been in OT with a hand specialist and also with an OT/PhD who specializes in musician injuries. He's had an x-ray and an EMG. No damage is seen from those two tests. He still has symptoms and it's definitely affects his playing. The working diagnosis is bilateral medial epicondylitis. 

Musicians: Any suggestions? Where to go from here?

what exactly are the symptoms?

I've been dealing with hip pain for a few years...finally gave in and went to a doc (sports medicine) after 6 months of severe pain that kept me awake at night....he didn't help and walked out on me because I can't afford copays for PT..when I can do the same PT at home by myself for free.

before resorting to that Voltaren helped somewhat.  It may be cheaper by Rx.  I had also used advil and the aleve at prescription levels for months.  narcotics didn't even touch the pain.

an injected steroid did help somewhat for about 2 weeks.

I've also been on meloxicam which doesn't seem to do anything.

out of desperation, I tried Doan's pills...i can't say its not a coincidence, but it's a lot better.  1st night, i made it through the night with no pain, but then was in severe pain when I straightened my leg.  2nd night no pain over night and moderate pain I could relieve with re positioning when I straightened my leg in the morning.  3rd night was MINOR pain that went away within a minute after straightening my leg.  4th night I had more pain, but had only taken 1 dose (instead of 2) the day before and didn't ice (it was just too darn cold!)

My nephew is studying music at Rutgers New Brunswick, focusing on percussion. I wrote and asked him if he could recommend faculty members who might have some experience with those kinds of injuries. I'll post if he answers but, to be honest, he's kind of a flake. However, I found this very interesting profile of a graduate student in the same program. I'll bet a few minutes on social media would find her.

Palm plays violin and viola and happens to have a medical degree. Her goal is to become a doctor specializing in treating injuries specific to musicians, who, like athletes, suffer from repetitive stress. ...

“I know of so many people in music schools, and people who have jobs in orchestras later on, who develop medical issues from singing or playing, and it’s so hard to find doctors who understand what it means to spend five hours in the practice room,” says Palm. “It might not be possible to say 'oh, I’ll stop playing for six or eight weeks.'”

Here is a list of program faculty and staff, including the head of percussion. It wouldn't hurt to drop him an email asking if he has recommendations.

I am aware of (but have no direct experience with) this system of promoting healthy technique for pianists:  https://www.lister-sinkinstitute.org/.

Wonder if there is something similar for percussionists.?

Thanks, everyone. I'll pass along these suggestions. Mostly I'm interested in finding someone who's had the same experience, someone who can say, "hey, the same thing happened to me and this is what I did that cured me."
