Unexplained rash

Hi everyone not been on here for a while as everything seems ok but today I have noticed I have a rash on both my arms and I don't know why, it isn't a heat rash as I don't sit in the sun because I don't like it and it doesn't like me so I was wondering if it could be to do with my under active thyroid.

Has anyone had the same problem or is it just me?

Have you just started or changed your meds as I got a rash when I started Armour. I stopped taking it and when I started again I didn't get it.


Could still be heat rash dont need to be out in the sun to get it


Hi could be so many things, allergies, new washing soap, your self or clothes, skin problem from having thyroid disease ( common).Eczema and Psoriaosis ( cortisone creams used ) I would see, if it does not settle see a GP. Although I have to say my G P `seem incapable of diagnosing even Skin cancers etc. I always ask 3 and then end up seeing a Dermy , as told , not, it is fine!

Make sure you use plenty of non allergic moisturiser , Also you could try HC cream, bought over the counter, so weak, it would not harm., but not on face.

Best wishes,
