Hey people for a couple of months now I have been playing guitar and been feeling wrist and tendon pain. It really sucks because now that I look back I know that my improper technique caused this. I used to fret chord shapes way too hard and play without breaks. I am wondering if anyone knows how to get rid of these pains so I can go back to playing guitar without pain anymore.

A doctors appointment looks like excellent advice. You might also want to look into an Alexander Technique appointment too.

Listen to your body. If playing the guitar hurts, stop playing.

take aleve, never play through pain and see a doctor/physical therapist.
all the best.
