Has the blister started to heal? If it hasn't, then you can certainly try and get it cultured.

The blister look more like rash or tiny dot cause i don see any watery or feel it when touching.
so should i go back and ask the doc to do the culture thing or just wait and finish my medication.
If he wants you to go back in 3 months for blood work, he is probably thinking herpes is a possibility.
Its very unfortunate that he didn't culture this, as that could have given you an answer now. However, it might not be herpes.

The doc gave me so cream to apply and ask me to come back after 5days if the blister still there, if is gone i need to come back after 3 month to do some blood test. pls help
