Suggest Cause Of Itching Pain Bumps And Swelling In Private Area

Hi im currently 24 weeks pregnant, about a month ago i developed pubic pain, it was put down to spd!!

But in the last 3-4 days i have started getting itching in the private area as well where it hurts. Just yesterday i found out i have bumps on the left side down there and it is very swollen as well!

It hurts more when i stand on the spot or walk for a while or when getting up from a sitting or laying position. I find relief only when i sit or lay! Do you have any idea what is causing this? I believe it is due to all the pressure from the baby and my growing uterus. thanks
