Spots/rash, itchy groin, irritation of upper thighs (inside), muscle pains, lumpy feeling swallowing turning head left, bruise, nausea, sweating etc..

Sounds unpleasant! That's quite a list! It also could be that some symptoms are totally separate from others. If this lasts over a few days, see a Dr to have a good exam. That will begin to get you on the best track.
Plan. . You have too many symptoms that requires doctor's evaluation. It's impossible to do it on line. Please make appointment with doctor. .
