Hello and welcome to Healthcare Magic. Thanks for your query.

Herpes usually presents as a cluster of small fluid-filled blisters which are painful. The blisters appear within 4 - 7 days of unprotected sexual exposure, then open up, releasing a clear fluid and can then form sores or ulcers. So, your description does not seem to fit into the icture of a Herpes infection. However, if a person has already had Herpes infection in the past, then subsequent infections or presentations may not be typical, i.e. they can just present with mild symptoms like just a pimple, or a small ulcer, etc. Sometimes such small white pimple-like spots can be seen in a called pearly penile papules. This is a very common condition and harmless condition and does not need any specific treatment.

So, if you have had a recent unprotected sexual exposure, then it's better to get yourself properly examined and tested, because the earlier appropriate treatment is initiated, the better are the results and further complications can be prevented.

Wish you all the best.

Hello again,

Thanks for the details. Since you have previously had some lesions (though not typical) shortly after an unprotected sexual exposure, it is possible that you could have had a herpes infection and the current pimple-like spot could be a resurgence of the infection. The only way to be confirm this is to have a blood test done (and as you rightly mentioned, the initial blood test which you had could have been too early to detect the antibodies)

The burning sensation in the base of your penis and the strange sensations going down your thigh could be due to the following possibilities.
- Prostatitis can often present with discomfort in the base of the penis.
- Local causes in the urethra like an infection, inflamation, stricture, etc. may cause such burning sensations or pain
- These sensations could also be indicative of a sciatic nerve roots). Sometimes, spinal problems can also produce these nerve compressions, resulting in these "paresthesias".
- Underlying inguinal lymph node enlargement can present with groin pain or a strange pulling sensation down the inner thighs.
- Certain conditions like uretric colic (due to uretric calculi / stones) can have a "referred pain" to the root of the penis.
- Sometimes, diabetes can also present with such burning / numbness

I would suggest that you get a proper physical examination (including a genital, abdominal and neurological examination) done by a doctor, in order to arrive at a definitive diagnosis.

Wish you all the best.
