Yes, yes, and yes.

Don't rely on Dr. Google for decisions about your pain relief. Talk to your doctor about your blood pressure if you have concerns. I have been told by multiple doctors that a OTC drug combo of Tylenol and Aleve is about the same pain relief as an opiate without the addiction problems. You "layer" them - ex., take one at 6 AM and the other at 12 - for extreme pain. This is the combo I use when the pain is particularly bad, and I have been using Aleve on a daily basis with generally good results.

As for your level of activity, it sounds like you may be in the middle of a flare. I can wake up feeling fine, but if I push myself just a little during a flare, I am down for the count. I would focus on rest and good food to improve your energy, but SEE YOUR DOCTOR about your pain relief concerns! And then learn to recognize the symptoms of a flare - the widespread pain and exhaustion - so you know to slow down and rest when one hits. Be aware that pushing yourself on a "good day" can result in a bad day - and that's on a regular basis; you'll have to rethink your activity level if you have recurrent flares. And oh yeah - avoid stress. If possible. Or get rid of stressors by cutting them out of your life.

Good luck - I have been where you are. Hugs.
