They look a lot like mosquito bites but they are in clusters and a lot smaller. I have a small amount on the lower back of my thigh and then a bigger cluster on the higher back half of my other thigh (near the beginning of my butt). I haven't tried or done anything new. They just started an hour or two ago. They went away and are now coming back worse. I just started getting a UTI today but surfing the internet I haven't found one case where a UTI caused a rash. Please help. Here is a picture if you can see them over my stretch marks.
