I hope that the ultrasound helped shed light and you are feeling better! I hope you will update us when you can!
Ive been on the pill for all of my cysts except the one 5 yrs ago. Im currently on a low dose pill.
I thought my initial spotting was due to stress, or that i forgot a pill the weekend prior, or poss due to the homeopathic "meds" i was on for a sinus cold. But the familiar ache wouldnt be there if that was the case.
I think my last cyst was 5 cm? Theyve all resolved in their own in the past. The pain this time didnt get really bad until it was time for my period.
The previous times it was mostly one sided pain, back ache or all across my pelvis. This one feels like a doozy!
All of your symptoms sound cyst related. The back pain, thigh pain, some what frequent urination, but you being on the pill should have seriously reduced your chances of getting a cyst. How large were your other cyst and did you experience symptoms with them??
