Hi, yes. Anxiety is driving your concern as oral sex is not a risk for HIV transmission. We are sorry to hear about your symptoms though. Please see a doctor to follow up on those so that you can have some relief. We wish you the best.
If you are the person who diagnosed the peripheral neuropathy that is not a diagnosis since you have no medical training.
Saliva inactivates HIV so you had zero risk for HIV. See your GP if concerned about your health since only he is capable of diagnosing if you really do have anything wrong other than fear getting the better of your reasoning.
