My scalp has been itchy, grainy and bumpy for a bit. Now it seems to have affected other parts of my body, specifically my legs. What is happening to me?
For context I have been dealing with an itchy scalp over the past year or so; has a grainy feel like sand when I run my fingers through with some stinging bumps that feel kinda like mosquito bites (not lice, 100% certain). Started using Selsun blue medicated with some success, the longer I leave it typically the better the result. Well last night after a show I got dinner at taco bell which made my gut a little bubbly (adding this just in case it has any relevance) I decided to just sleep through it since it was already late. While I’m trying to fall asleep I feel a similar stinging/itching to what I get on my scalp but on my leg. I go to the bathroom and my leg is covered in these little white bumps that feel hard and raised on my skin. When I scratch them a bit some of them seem to dislodge like sand. Itched so bad last night that I could barely sleep 😔 any ideas of what could be affecting me?
