Thank you for the pictures. I am sorry for the time to type an answer, but I wanted to address what can be done for the rash, not simply answer the direct answer of whether it could be a heat rash. Yes, this does have an appearance consistent with heat rash, also called miliaria. The fact that it migrates is also common with a heat rash. Heat rash is more often seen during the summer, but can be seen in the winter if th skin gets locally hot and the skin gets dehydrated. If you manage it as a heat rash and it improves, that would also be strong evidence that it is a heat rash. For a mild heat rash, the usual approach would be the use of lanolin to help hydrate the skin without obstructing the pores of the skin. Products that contain petroleum jelly or mineral oil can block pores and possibly exacerbate the condition. Bathing or showering in cool water using a mild soap also can be soothing. If the heat rash is more severe and causing symptoms beyond just the visible rah, calamine lotion can help sooth the rash and particularly can ease itching. With a more severe rah, a course of topical steroids may be necessary. Since this is only slightly itchy, it will likely respond to the use of lanolin and avoidance of petroleum jelly and mineral oil. If I can provide any additional information, please let me know.

Thank you so much ..
I'm bipolar and am managing without my meds have been for 4 years now but when somethin like this comes up it worries me .
So definately think it's just heat rash.
It came up about 40 mins ago and had disappeared now
It certainly has the appearance of a hear rash, and the fact that it resolves quickly is indicative that it definitely is not anything serious, as all serious rashes will last longer than 40 minutes.

It just seemed weird as my feet were freezing cold .. How can you have heat rash but cold feet lol
It is due to the heat in the skin and blockage of the pores in the skin.

It's flat under the skin and not raised thought
That is OK.
Customer: replied 2 years ago.
So heat rash can be under the skin not on top. Sorry to be a pest
In cases in which it is mild and transitory, it may not develop a raised rash.

Ok thank you so much . I can relax now . I'm buy Dom hydrocortisone cream tomorrow that should help shouldn't it
As a steroid, it is one of the interventions noted above, but we would usually prefer to perform the interventions as noted above.

I had a mirena cool fitted 8 months ago and this is the first month I haven't had a period could the rash be linked ?
No, that would not be related. A sin rash can occur as a side effect to the Mirena, but it typically would not be the transient, migratory rash such as you are experiencing. It also would typically occur earlier in the course of use of the Mirena.
