Absolutely and it sucks! When I get that tired I get pain in my ribs too. My rhemie said its just the cartilage and everything in between the ribs that are inflammed and causing pain( just like in your joints)Costrochrondritis I think?? That pain in my ribs is a huge sign I am starting a flare. For whatever reason it only happens when I am feeling really bad.
I get numbness and tingling (like my hands or feet are asleep) frequently too. I would have that checked out though. It is definately a sign of circulation problems and even clots. It sounds like neuropathy though. I think a few people here have it, I am sure they will respond.
As for the sleeping all day and night I feel like I could do that everyday! I hope that helps, and I hope that you are able to stay rested for a few days and start feeling a little better soon.
