<s>[INST] I have a small blister on the inner lip of my vagina, and some lumps around my anus. i have experienced no pain or itchiness in that area but i have had severe stomach pain and a recurring bladder infection. Since the blister appeared it has been painful to pass urine and I have just finished my period, which was unusually heavy. i have been tested for chlamydia and it was negative, and i have been examined and the doctor has noticed nothing out of the ordinary.  i have had urine tests which showed blood and protein, but a ultrasound scan showed nothing. i feel as though i am getting no diagnosis and recurring pain / more symptoms. [/INST] Hello and welcome to Chat Doctor, Presence of painless blisters in the vagina could be due to many reasons. It could be due to herpes simplex infection or some vesiculobullous lesion. Since the lesion is painless and is non-itchy, the possibility of herpes simplex is ruled out. Lumps around the anus could be due to thickening of underlying fascia or growth in the soft tissue. You need to get a clinical examination by a gynecologist and/or dermatologist. Thanks and take care Chat Doctor.  </s>
