Hello,
If you could please describe the precise lesions you see or how you feel them, estimate the size by comparing to a known object. Locations of lesions, clustering or not. The
dermatosis you are having might not even be directly related to your
pregnancy. But if they are pregnancy related, then you should allow sometime for
hormonal balance to be established in your system and suppress the symptoms by either applying
hydrocortisone 0.05% cream on the lesions or taking oral antihistamines.
Another possibility is if the above treatment doesn't work, you might be having scabies ( strange right? but it is quite possible given the locations you have mentioned). If that is the case, you'll need to take appropriate treatment with anti-scabies lotions.
Your daily skin lotion too, should be re-checked as it might be the cause and by stopping and switching your soap might help your situation.
I will suggest you pay a visit to a
dermatologist for close examination and proper management if above do not work.
Not able to examine the rashes myself makes it difficult to give you exact management.
Best wishes and regards
