<s>[INST] hello! I have been on my menstrual for little over two months (on bc) have had ultra sound, I have severe pain right lower back side with tennis size balls blood clots I am having accidents in my clothes what else can be done please help and all blood work is normal [/INST] Hi, thank you for posting.I have gone through your query and I understand your concerns.Based on your symptoms I can say that you suffer from endometriosis. Another possibility is that you suffer from hormonal disorders.To treat this condition you should use antibiotic medications, progesterone and non steroidal anti inflammatory medications.An antibiogram is necessary in order to determine which is the right antibiotic for your case.Contact your gynecologist to discuss about the diagnosis and treatment.Wish you good health.Dr. Behar. </s>
