<s>[INST] hi, last february i had a lump under the skin of my upper right inner labia minora. like the size of a pea. its hard, not painful or itchy..it appeared during my period. my doctor said its just a pimple and not to worry and gave me oral antibiotics and bactroban ointment..it went away after 2 weeks..however just today it re-occur on the same spot and i also have my period today. can u help me. tnx [/INST] hi.based from your description, it could be a Bartholin's cyst. it is best if you consult with an OB-gynecologist for medical and physical examination. medical and surgical (excision) management will be directed accordingly.hope this helps.good day!!~dr.kaye </s>
