I am more just worried about accidentally hurting him since he flinches so much if I mess with it. It may just be a "hey don't touch me" response, but it could also be a pain response and I have no idea which it is. Supposing it is wedged somehow, what would be the safe amount of time to just watch and let it resolve on its own. Is there a cut off point where intervention would be recommended? I mean for instance if he sheds and it was stuck between the scales it would resolve with that right? If it is in his intestines somehow is it safe to wait possibly weeks until he has a bowel movement?
He doesn't flinch or act like he is in pain if I press against the surrounding area or otherwise touch his tail, he only gets wierd if I move the fiber itself. However, I wonder if this is a good sign, as one would think internal injury or swelling would mean tenderness or discomfort around the entire area.
