Good luck Fernando - sometimes the body is stronger after healing, so don't rule out anything yet.
I second that statement. I have twice recovered from long standing / chronic injuries - and found that the area(s) of the body concerned were much stronger and now injury free , after the event. Also , I have seen athletes undergo quite involved ( and initially very delicate ) surgery - then go on to break new records some months later.
Mainly; I wanted to say sorry for joining this thread rather late - and wish you all the best for an effective recovery. So often, being forced to stop and address an issue like this , is a blessing in disguise, the only way forward.
I wish you good health . :)
