Very interesting! Thanks for that link. You are a handsome guy!

I see you play guitar? So when do you school teach and what do you teach?

Playing that guitar could be straining you as well as your injury.
My son plays the base, and he often has trouble with his hands.
Nide44 here also plays ... it can be stressful on the shoulders and hands over time!

I think you should be exploring chiropractors (don't know what you have in Portugal), and/or physical therapy. You might benefit from some cold laser, or IFc and ultrasound. Not everything is drugs you know
