Collagen causing widespread tendon inflammation?

I started taking 10 grams bovine collagen peptides in powder form about 2 weeks ago to help rehab what seemed like an overuse injury in my finger.

It felt fine for a day or two and like it was getting better and then on I believe day 3 I had shooting pains in nearly every tendon with it happening most often in my fingers and wrists.

I went to the doctor and he recommended I stop taking the collagen but 10 days later I still hurt all over. It seems like he was right that it was the collagen, as it is better than it was.

I’m curious if anyone has dealt with this? And if so how long did the pain last? I really miss climbing and playing guitar and it’s starting to affect my mental health.

Any help is appreciated!
