first of all u will have to stop further irritating ur skin so that it heals (it can take 3-7days to heal). so arrange an alternate work until then. two, take vitamin c
500mg - 1000mg daily, it speeds up healing. and to avoid recurrence use "lube" a jelly used for doing sex or just use a simple non medicated cold
cream or an aloe vera
gel. hope it helps and u never suffer again.
