i'm assuming the splotches go away eventually after your shower? if so it sounds like you're describing a normal situation. whenever a person takes a warm or hot shower the skin's blood vessels dilate from the heat. this causes two noticeable effects. first dilated vessels within the skin become much more visible. second when blood vessels dilate there's less pressure inside them. less pressure means it's harder for the heart to pump that blood all the way up from the feet to the chest. so when you see those blotchy patches on the lower extremities after a shower you're usually just seeing areas of dilated blood vessels. this is not a dangerous situation like a blood clot or anything. it's a normal phenomenon that occurs to a lot of people when they take a hot shower. it is especially noticeable in fair-skinned people because the blood vessels are much easier to see. wishing you well!
after showering i have red/blotchy patches on my legs what are these? . so i have the shower on about 39 degrees celsius and was in there around 5-10mins due to a hairwash. after i had finished i noticed around my knees/shins were purple with red blotches going from my knee don the side of my leg and onto my food more so on my right than left leg. they were not tender nor raised just seemed like a discolouration. this has happened before just wondered what it was?
