Re: ovarian cyst symptoms but neg. ultrasound
You know your body better than any physician so if you feel that your concerns are not being taken seriously, find another doctor ! I am wondering also if you are on any type of birth control. If so, this would be the first obvious thing to check out. I was on the pill for about 20 years and I began to experience endometrial atrophy. The lining of my endometrium was so thin that it became fragile and started to bleed. I also experienced painful cramps and strange sensations. I finished off my last packet and did not start another. The pains went away as did the strange pulling sensations and in my case, the irregular bleeding. I have an 8 cm simple cyst on my left ovary and do not have any symptoms. I actually thought that the pains I was experiencing were due to the cyst but 10 months after my first ultrasound, I am not experiencing any pain. Endometriosis is also a possibility and an ultrasound would not be able to detect this. Only a laparoscopy can find and remove this. Another possibility is your appendix.
At any rate, you need to find a doctor who will listen to you. Many doctors have this terrible habit of thinking that women are crazy idiots who complain about nothing. If you think there is something wrong, do something about it. The kind of pain that you are describing is not normal, especially if you have not changed anything in your life recently (ie. began or stopped birth control pills or changed medications etc..). Find a doctor who will take you seriously.
I hope you get some answers soon. Take care.
