Hi, thanks for sharing your health concern with team HCM!
In the present case of itchy tiny perineal / back swellings or lumps, if I were your consulting physician, I would just consider 3 possibilities like:
1. skin papillomas or warts
or benign fibro-epithelial polys
2. infection / fibrosis
of multiple hair follicles
3. skin infection
due to fungus, proctitis
, piles, fistula or worms!
As per your description, I would like to advise you seitz bath with cetrimide antiseptic solution and apply calamine
lotion for itching and go for stool examination before farther medication!
Take caution not to get injured there as this might invite infection.
Hope you got your answer. Please feel free to write to us if any more queries or with the reports / follow-up...
Wishing you the best health!
