Yes, I have the exact rash. . It stopped spreading and stopped itching after 2 weeks of using a cream that cost 30 from my doctor...
It was an anti fungle cream that is ok to use if your pregnant.
The doctor Dodd not tell me how I got it, just that it like it might be caused by a change/irritation of new things, dog dander, different foods, exposure to different perfume or something. ..
I'm telling you it was not anything like that. ..I solo have no idea how it happened, just it was itchy and horrible. . I'm glad I stressed my concern to my doctor
If you can I would get it checked out. Swelling sounds like something a doctor should look at.
The markings kinda look like spider pe snake bites. Ive not been bitten by anything bit yhats what it looks like and it kinda swollen up aswell as very sore. I can hardly move my arm some times because of it.
I dont know about the markings but yes rash can be pregnancy related. A friend had one really bad her last trimester.
