I think you may be having steatocystoma multiplex. They are cystic lesions. The cyst contains chalky material. The condition is benign. It is not dangerous unless the lesion becomes infected. You may take antibiotics ,if infected. Otherwise it may be kept untreated. It is not dangerous. If it is embarassing, you consult dermatologist
. He may excise the cysts under local anaesthesia. The procedure is done in OPD and it minor surgery. I hope you got my answer.
