Hi dear, you do sound like you’re having an emotionally stressful time.. juggling work and taking care of baby too. Can someone help you? With baby care..
Sleep naturally produces antihistamines, but if you’re not sleeping well, you’ll be more sensitive and be itching a lot more. Of course, please take the medicines given by the doctors.
There are some anti-itch creams you may consider applying, or calamine lotion, which is also safe if you’re carrying baby.
Lastly, I had very sensitive skin with rashes too within the first year of giving birth. I became more sensitive to dust/dustmites, etc, within my house. So cleaning my house more and using some anti-dustmite household products did help.
Hope you get better soon!
