My 13 year-old daughter has recently-diagnosed Hashimotos and is on 50mg levothyroxine (GP has said will likely end up on 100). Just in the last few weeks she has developed a dark-coloured rash/dark pigmentation around her throat and chin area. It is occasionally itchy, but not raised or dry like eczema. I just wondered if this is linked to her condition, if anyone else has experienced something similar, and if so did you find any effective treatment? In lots of ways this is a minor symptom compared to all the other interesting things Hashimotos has thrown at her, but as you can imagine it really bothers my teenage daughter to have to deal with something so visible. we are seeing the GP next week to go over her most recent blood tests, so will check in with her about it too.
I'd be very glad to hear from anyone who might have an idea about this
many thanks, D x
