Fish oil and curcumin are stables in the diet. I tried the voodoo flossing a few years ago for a golfers elbow, didnt get much results.
So far what worked best, unfortunately, is resting. I was away for 2 months and that was the best when it felt, but the pain came back again once I hit weights.
Very high rep (100-150) tricep extensions with 10 lbs KB’s pumps the elbow a lot of blood and helps. I think it will go away in time like other long term injuries…
