pls help!!!

Iv

I feel sick and terrible. Today my body aches badly, I don't know if its the workout but why today? I was feverish too. There's a cut between my anus and vagina, so could that be the cause of the fever? I have a sharp headache too which is one sided. Been sleeping a lot in the afternoons too which makes me even more tired and spoils the rest of my day. I just had pain killers (paracetamol). Please what more can I do?
