Fibro makes all pain worse. There probably isn't much past heat you could do for that pain but in general by eliminating sources of pain you will feel better overall. im going to use food as my example. With fibro eating something that causes low level inflammation, like sugar, will cause severe pain because of that inflammation in our body, where as someone without wouldnt even notice the difference. Your going to have to experiment and log and see if you can't find specific causes of pain and see if you can find ways around them. Some things you just have to try to get through, like pms and weather changes.
Sounds like a cyst. Good news they are usually nothing to worry about and go away during your normal cycle. The ultrasound will show if there are any cysts. The main reason I think it is a cyst is because it hurts when you ovulate and it hurts to sit. Two tell tale symptoms.
Are you afraid of having the ultrasound or what they may find?
I am waiting for my laparoscopic surgery in my pelvis area on May 31st. An abnormal cyst and ovary will be removed and they well confirm whether I have endometriosis or any other abnormalities. I am allowing them to take out more if there is lots of damage.
For me the pain is unbelievable and not knowing what is exactly wrong is driving me BONKERS.
