Hi...dear user.,
Thanks for choosing HCM.,
Bigger than pimple, no pain, no itching could be...,
WART or ACRODON..,commnly seen in the armpits and neck areas.,
There is no medicines for this.,
1) Radiofrequency (RF) Electro-cautery...will remove the lesion .,
without any side effect..,
2) During shaving , it will spread and infect .,
So don't shave that area, only trim the hairs by trimmer.,
hence consult good dermaqtologist and remove that lesion...good luck
