I am 29 years old man and had protected sex with a sex

Hi doctorI am 29 years old man and had protected sex with a sex worker 6-8 ago. After 4-5 weeks of this incident, I started with penis pain, burning pain during urine/ erection, it was worse when sitting i also developed muscle pain needles and pins all over body (especially forearm, thigh and legs)It lasted for 2 weeks, with mild fever for 3 days due to stress and anxiety I think due to this incident. I went to GP and he quickly tested my urine and said he thinks it is UTI, so he sent urine sample to lab and prescribed nitrofurantoin 50mg which I completed the dose for 1 week.I was told that my urine lab results came normal. Despite completing my antibiotics, I still have tingling pain all over body (penis pain is much better though)I am very much worried about this condition and reading on internet about HIV , since then I am very scared and stressed thinking I may have been infected.I DON'T have cold, soar throat, fever, diarrhea,I HAVE tingling pain on (right hand is most affected) finger and forearm,
I HAVE tingling pain on (right leg is most affected), thigh and shin
I also get tingling pain on random places on body
It comes and goes
I notice this pain worse when sittingDue to stress, I start headache in the evenings.. but when I wake up, I feel fresh and healthy -- as I think about my condition, it is getting worse and worse.Please advice what could be the reason for my condition, could this be HIV or anything else? that's very scary. Please help
