hi, a relative of mine, after being out and about more than usual, thus not getting to put her feet up, says she has red legs after showering. She also has edema, not related to showering. I have had something similar (in the past when more able to go out). Is this from POTS? ETA: she is diagnosed with POTS (they did not do TTT) and I told her to email her doc; I just wondered if others with OI have similar.
