1) If there is a liver infection or kidney infection, it is likely that you will experience more symptoms which are severe.
2) you will only develop symptoms after the incubation period, which from your timeline sounds unlikely
3) it is unlikely that hep is transmitted through your exposure, it requires transfer of bodily fluid.
4) there seems to be lots of other more probable causes of your symptoms. An analogy: it does not mean i have a brain tumour if i have a headache. It can be caused by something else.
5) Go see a doctor instead of trying to figure this out on the internet.
I still am feeling some pain on right side of my back near to buttocks. Could it indicate any std kind of infection?
Rubbing could expose you to herpes, syphilis, some parasites and fungal infections. I think you should visit your doctor to check where is that back pain coming from, but I don't think it's due to a STD. You can also test as follows:
-6 weeks after the exposure, for syphilis, and if you get it negative result, repeat the test 3 months after the exposure, as there are people that take longer to show a positive result.
-3 months after the encounter, for herpes.
Regarding fungal infections, if you see you feel any itchy sensation in your genital area, visit your doctor. They are really easy to treat with some creams. Same thing for other external parasites transmissible through contact skin to skin.
All the best.
Can any expert pls answer here? Help much appreciated
