The lesions that you have just described could either be due to irritant reaction of your hair removing cream or it could be herpes
infection also. The definite diagnosis can only be made once the lesions have been thoroughly examined and proper history has been elicited. So you need to visit a dermatologist
for the same. Keep the area clean by using warm saline water. Do not use harsh soaps, betadine
etc over the involved area. Apply an antibiotic cream and you can also take cetirizine
to reduce itching or a pain killer to reduce pain. However, this just a general treatment, a doctor's visit is must. Take care.
