A few months ago I felt what I'll describe as a band around my ribcage just under my breasteses. I had gained some weight so I thought maybe it was from that. It was there and noticeable but nothing horrible. About 2 weeks ago it started getting worse. When I wake it's like it was but within a few hours it feels very tight. I am not in pain. It is just there feeling like someone is pressing in. I also have what feels like muscle aches/spasms on my back under my shoulder blades. This also moves around some, going lower and was gone for a while but just came back. I'm not in pain. It is just tightness. When I'm up and moving around, it is much more tolerable. It really feels like my muscles are just "cramping" or something. Any thoughts? Minks Let me add that my feet are so cold it's painful. They feel like there is a band above my ankles and everything below that is cold. UPDATE: I took Tizanidine last night (muscle relaxant) and when I woke I had no tension. But now, 2 hours later my back is in spasm. I took some potassium to see but it did nothing. This seems to be out of nowhere. I did nothing, not really stressed. By the end of the day it really hurts.
