Skin Pain

Hello, my name is morgan. I have had multiple symptoms that I can not find answers for. I had an iud inserted about 6 months ago and since then I have had several yeast infections, and I think im getting a bladder infection as well. I also have been experiencing weird skin pain on my upper thighs. It feels like a sun burn, but I never really go out in the sun, and my thighs certainly dont see any sun. Along with the skin pain, im also having mild joint pain in my groin area, please help if you can come up with some sort of answer to my questions, thank you
