Brief Answer:
History and Pictures requested

Detailed Answer:
Hello,
Thank you for posting on HCM.
I can understand your concern regarding the skin lesions but its difficult to point specific diagnosis in absence of clinical examination.
From your description, it seems like most probably you are having a fungal skin infection called Tinea or it can be intertrigo, which is an infection which occurs over any opposing skin surfaces , mostly seen over groin folds. Its caused due to bacterial or sometimes fungal infection.
I can understand its difficult for you to provide clinical pictures considering the sites affected but I would be glad if you can manage some good quality pictures so that I can help you in a better way.
You can either post pictures directly on the page or can mail pictures to YYYY@YYYY
with subject titled ' ATTN Dr Hardik Pitroda'.

Apart from the pictures, a few details in history would be helpful:
1. History of similar condition in any of your family members
2. History of similar condition in past
3.Your job profile and occupation especially history of long distance traveling on frequent basis.
4. Any co-morbid conditions like Diabetes

Thanks
Dr Hardik Pitroda

Brief Answer:
Oral Valacyclovir

Detailed Answer:
Well, considering your history of burning sensation with no visible lesions, I would like to treat you provisionally for Herpes Zoster. Its a kind of viral skin infection producing painful rash and blisters along particular nerve trunk distribution. People having diabetes are particularly susceptible due to declining immunity.
Since it could be prodrome of herpes, the lesions are not yet visible.
I would recommend you to consult a dermatologist in person for better management.
In your case, I would recommend following line of treatment:
1. Oral Valacyclovir 1g thrice a day for 7 days
2. Oral gabapentine 300mg thrice a day
3. Oral amitryptiline 25mg at night.
Let me know if you require any more assistance from my side.
Thanks
Dr Hardik Pitroda

Brief Answer:
Herpes zoster is not a STD

Detailed Answer:
The lesions of herpes usually appear few days after the prodrome. Sometimes, the episode of herpes is abortive and it just produces symptoms of burning pain without any obvious lesions. Herpes Zoster is reactivation of inactive varicella virus which causes chicken pox. Its not a sexually transmitted disease.
Patients of diabetes and similar immunocompromised condition are prone to develop herpes zoster.
I would suggest you to go for the treatment I highlighted before in my answers.
Take care
