Sometimes people under estimate the importance of treating pain. But pain itself can make a person sicker and untreated pain tends to escalate into worse and worse pain. I try to get address pain in my patients while it is mild so that it doesn't escalate into more serious pain. And often I try to think outside the box - position changes, diversion, massages, mild heat or cold, topical pain creams and etc. That doesn't always work of course - but sometimes if I can get some pain cream on a person's knee and get their leg elevated before the pain is serious - I can prevent it from becoming serious and they might have an all round better day.
We are often taught to /tough/ out the pain - but I find that pain people attempt to /tough/ out often snowballs and even delays healing.
The other side of it is of course that every pain pill comes with side effects and draw backs, so it can be a very delicate balance and often care providers are walking a very fine line when trying to address pain.
My best advice is to make sure your care provider knows the level of pain you are and how it is effecting your life.
And I feel for you - I have autoimmune issues and have many relatives with autoimmune issues and it is a hard path to walk.
