hi, i am Renea. for 2 months after i gave birth to my son, i have developed a rash on my arms. Sometimes it itches on my legs and back. It seems to itch worse at night or when i get hot or alittle flustered. I am online looking for answers and all these people going to the dr. s about it and them not getting any answers. I even called my obgyn and she has never heard of it, which is hard to believe. I just want to know what is the cause of it, is it hormonal or what and how long does it last. Do i need to go to the dr for medication to get rid of it cause some people said medication did not work for them. I just want it to be over with it makes me irritable.

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 dermatitis 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 HY Chat Doctor. 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
