It’s been bothering me since December, it comes and goes every month, it didn’t itch before but now it does heeeeeeeeeeeeeelp 
based on the blisters on your lips it looks similar to herpes but do you have blisters on your genital area recently aswell? because that can be a strong indication that it is herpes.
No, I don’t have any sign or symptoms on my genital area,
I took acyclovir pills but they did not have any effect 
go get tested for herpes 1&2 Igg believe results not people
Dear dora,
This is angular cheilitis, not herpes. It is frequently caused by candida ( a yeast infection) and/or staphylococcus (a bacterial infection).
If it’s quite itchy, it is more likely to be candida so try to get Canesten, Canesten-HC or Daktacort ointment from your local pharmacist or drugstore and apply it twice a day to the affected areas for a week or so.
Adhari.
