I started playing the bass around two months ago. However, I was playing 2-3 uninterrupted hours a day with relatively poor technique and no strap, and around 2 weeks ago I developed tendonitis down the ulnar nerve of my fretting hand. It’s the most pronounced in the pisiform bone at the bottom of the pinky. I also get some pain on the side of both elbows. I took about a week off icing and taking Advil, but it still feels pretty much the same. Has anyone else ever dealt with this kind of injury? What exercises can I do and should I stop playing entirely as long as this persists?
