I agree if you can call your pdoc and/or T to try to get some relief before it gets worse.

I am glad to know you have a boss who is aware, understands, and does her best to support you rather than shy away from things.

I know she has given you compliments on your work but another thing to also consider is that she is being so supportive, she must be doing that in large part because she considers you a valuable employee and wants to keep you happy and healthy so you can continue working for her. She may be a nice person but she is still a boss, she wouldn't put so much effort into helping you there if she didn't value the work you are doing.

So consider her actions as well as her words when evaluating your value there. And do everything you can to take care of yourself and help yourself through this.
