Skin allergy after giving birth?

I’m now nearly 5 weeks postpartum. In the past 3 weeks I’ve experienced weird skin rashes, bumps and patches on legs and arms that come and go, worst of all I feel itchy everywhere. I have not experienced this before and I wonder if it’s some allergy or condition caused by hormonal changes? I’ve tried to moisturize with VE oil but it doesn’t help.

Will ask the doctor at my 6-week check up but worried that the clinics could be closed due to the virus situation.

Anyone share this kind of experience? I’m scratching myself raw 😣
