I woke up 2 days ago with the inside arm crease swollen up. It's not red or warm. Just hard and swollen, not tender when touched either. When I bend my arm though there is a bit of discomfort. When I bend my arm the lump or swelling seems to disappear. Only when it is completely straightened it is visible. Anyone ever have this???
it's typically a swollen lymph node--either from an infection nearby or yes, fibro makes lymph nodes swell suddenly. They may or may not be tender (mine are)
