I'm trying to get an answer on what this rash could be
Left buttock
Had for a week

mysticdoc :

The views expressed by me are for educational purposes only and do not establish a doctor patient relationship.

mysticdoc :

Hello,

mysticdoc :

Thanks for your question.

mysticdoc :

Is the rash painful or itchy?

mysticdoc :

How does it look like?

mysticdoc :

Is it possible for you to post a picture here for better understanding?

Customer: I'll p,dot a picture
mysticdoc :

ok

Customer:

Full Size Image

mysticdoc :

Is it painful?

Customer: I would say sensitive more than painful
Customer: can your see picture ok.? Not the best
mysticdoc :

any insect bite or bed bug you think of?

Customer: no
mysticdoc :

ok

mysticdoc :

this is likely hair follicle infection or folliculitis.

Customer: does it look like shingles or herpes, I hope not
mysticdoc :

Shingles is another possibility

mysticdoc :

Shingles look more red though.

mysticdoc :

and more painful

Customer: I went to a doctor yesterday am
Customer: he looked at a picture I took 4 days ago first and his initial reaction was shingles. Then he examined me and said maybe not
Customer: i asked about herpes (hsv 2) because I had massage and hand job ( stupid) on 12/11/12' she was full clothed and I was naked , no oral or genital whatsoever. He ordered ImG and Igg and now I am freaked.
Customer: He said it was to reassure me. He offered no other explanation of what this rash could be.
mysticdoc :

Ok

Customer: What do you think
Customer: I'm really scared
mysticdoc :

the lesion can be cultured

mysticdoc :

this is to definitively rule out herpes.

mysticdoc :

Another option is to try an antibiotic course to see if the lesion resolves.

mysticdoc :

I will suggest a herpes culture --will be more accurate than the blood test since you have the rash

Customer: He said he said could not culture it because no fluid to send to culture
Customer: Does it does it look like herpes to you, have you ever heard of transmission this way
mysticdoc :

That is not a common ay of transmission.

mysticdoc :

And since there is no fluid this is not likely herpes.

mysticdoc :

Herpes lesions will contain some fluid.

mysticdoc :

sounds more like bacterial infection.

Customer: How long does lesion have fluid
Customer: Reason I ask is had this for about a week
Customer: You still there?
mysticdoc :

the lesion should have fluid for at least first 2-3 days

mysticdoc :

then they dry off.

Customer: So not sure whether there was fluid or not , been a week or maybe 4 days
mysticdoc :

ok

Customer: Anything allay my fears?
Customer: anything to allay my fears?
mysticdoc :

it is not common mode of transmission.

mysticdoc :

The location is in the butt -not in the genital area

mysticdoc :

and does not fit the classical herpes lesion

Customer: How is classic lesion different than my picture? Sorry to rifle questions but trying to cope with anxiety
mysticdoc :

they more erythematous or red and more blister like

mysticdoc :

also the spread will be wider not just one small area

Customer: I'm worried about the test he ran, I know that was clear 11 months ago and have had zero sexual activity ( not even casual) since this incident on 12/11/12
Customer: meant to say was tested in November 2011 Igg 1 and 2 and was negative
mysticdoc :

This will most likely be negative

Customer: you think so ?
mysticdoc :

yes

Customer: If it was shingles would Igm show positive for antibodies , in which case I wouldn't know if shingles or hsv 2?
Customer: ill end the questions soon, promise , appreciate your patience
mysticdoc :

shingles will not cause HSV2 positive

mysticdoc :

IgM will be positive in ecent infection.

Customer: but will Igm distinguish between shingles and hsv 2' that's my worry too
mysticdoc :

yes it will.

Customer: reallytoo really?
mysticdoc :

yes

mysticdoc :

for shingles different test is used VZV antibodies

mysticdoc :

Shingles is a different virus same as chickenpox

Customer: i don't think he ran that
Customer: yes I had chickenpox as an infant
mysticdoc :

ok

mysticdoc :

ok

Customer: he seemed to order just the IgM and Igg
mysticdoc :

you may get shingles but this will not cause positive HSV test

Customer: thank you for that
mysticdoc :

Shingles is not same as herpes simplex virus

mysticdoc :

very welcome

Customer: to summarize, tough to say what it is , your guess?
Customer: to clarify if shingles, will not show up on IgM
mysticdoc :

it is not tough --likely a bacterial infection

mysticdoc :

can be a pressure rash also from pressure or scratching

mysticdoc :

herpes unlikely

mysticdoc :

shingles distant possibility

Customer: if your right and I so hope you are I'll owe you, have not scratched or touched so not pressure rash
Customer: I wish I could diminish severe anxiety over herpes
Customer: Again, to clarify, if shingles will not show up on IgM test?
mysticdoc :

no shingles will not show up.

mysticdoc :

i will be very surprised --as they do not look like herpes at all.

Customer: thank you again
mysticdoc :

very welcome

mysticdoc :
