Have they measured your rib expantion? You may be fusing and losing rib expansion frown I find that when I have flares in my mid back I struggle more with breathing and I just found out that Im starting to fuse there. I would look into it.

As for night sweats I get them all the time some nights they are so bad I have to get up and shower and change the sheets (my husband loves being woken up for that lol)

But do bring this up to your doctor it could be anything

Hope this helped

When you live with chronic pain, you never tell the truth. When someone asks you how you are or how you feel, you lie & say, I'm fine or I'm OK, & you smile.
