Some pain can be useful and informative. I view it as a teacher of sorts. Silence it and you may miss the lesson. Work with it and it may pay off with benefits.

It is hard to quantify "pain." What is too much for me may not be too much for you and vice versa. The important thing is that it is trying to TEACH you something. It is not just there to annoy you. If it screams at you and you can't hear the lesson through the screaming, well then that's that. I've taken ALL degrees and tried to catch the lesson. Sometimes I'm successful, and sometimes I'm not.

Patience is a virtue. Remedies are not overnight.

Perseverence is a virtue. Some things require that we continue even if we do not see/feel results/better.

Sometimes what feels better may not necessarily be doing you good. If in the long run it does, so much the better.
