Throbbing In Clitoris Area, Bladder Fullness After Urination. Spots On Chest, Neck, Back. Any Remedies?

I have been suffering for a couple of days with a weird sensation in my clitoris area after I pee. There is no pain or other signs of anything wrong in the area, only at the end of peeing and after. It's almost like a throbbing, and also I feel as though I still need to pee, like I've held going pee for quite some time, and since this issue I've been getting spots on my chest and neck area, and possibly my back. They don't itch unless I'm warm, I read somewhere that they were linked but I'm not sure how or what it is or what to do to get rid of both things.
