All the time, right side. Not only a knot feeling, but like a brick, or cement block. Tense. I had ultrasounds, CT to rule out medical problems. It seems that certain movements, posture, and tight clothing (bra) can irritate the area. Flares can last for weeks. The discomfort slowly progressed to pain throughout the years, probably about 5 years now.

I get these 'knots' in a few places: couple of spots on the front rib cage, calves, groin and back of legs can all get fired up. I often have hard lumps too that can turn into bruises over a couple of days (always the possibility they bruise cos I fiddle with them) but in short, yes, these knotted feelings seem to be par for the course for some people with fibro, for others the pain is more generalised but sometimes also more intense. It's a slippery little sucker this fibro.

Yes u get this knot feeling on the left side under my rib, and pain at times.

Thanks for all you had replied. It is definitely annoying. I know sometimes I might get a random sharp pain at same location but for the most part it just feels like the knot feeling.

yes
