I have tested all STD post 20 mon after sex, negative. I feel low gr fever swollen lymph nodes, drymouth, urine cul came as cloudy, help me?

Hey man! Cloudy urine means nothing. You haven't listed your temperatures, but if you're not frankly in the "fever" range, I doubt this is a sign of sickness. Glad you're STD-negative. Do you have any very enlarged lymph nodes worth biopsying? Been checked for infectious mono? Might you be feeling unwell simply because you are lonely / in a situation that's interfering with your meeting life goals?
