Hello,
The pea sized lump outside anus looks like a blood
blister. Your symptoms are indicative of
Molluscum contagiosum. Molluscum contagiosum causes lesions, called papules, to form on the skin. The papules may be clear, yellow, flesh colored, red, or pink. They are firm and smooth. they may look like blood blisters.
When molluscum contagiosum is transmitted through sex, these lesions commonly develop on the lower stomach, upper thighs, anus, and genital region. Molluscum contagiosum sometimes goes away without treatment, but this can take several months.
Applying topical ointment that contains
podophyllotoxin,
salicylic acid, or potassium hydroxide on the affected area is helpful. Get clinically examined by a GP, the treating doctor may remove papules with lasers or by freezing them off.
In case of
pimples, it occurs when pores become clogged with oil and dead skin cells. A clogged pore may fill with pus, resulting in a pimple. Do not pop these pimples, as doing so can result in infection. To treat or prevent anal pimples you should keep the area dry and clean. Avoid shaving or waxing the area and eat a healthful diet.
Take care. Hope I have answered your question. Let me know if I can assist you further.

Dr. Nupur K., General & Family Physician
