For days after my cyst collapsed (partially ruptured) normal things were extremely difficult - laying down, walking, sitting, going to the bathroom, eating and drinking all caused me pain. This was due to the excess blood in my abdominal cavity which was bothering the things inside. It took about 4-5 days before I felt relatively normal again. During these few days, I searched high and low to find things to ease the pain. I wasn't able to come up with much except for things like chamomile tea (which didn't do anything) or beetroot (who has that). I however found some things around the house to help ease my pain. I hope that they can help you too.
1. Heating Pad
PS - Even though I am a back sleeper, I found that sleeping on my stomach with a heating pad under the affected area was the only way for me to get any rest. The way that I know that the heating pad was helping was because I kept waking up every 2 hours when my heating pad turned off from the automatic shut-off.

3. Abdominal Wrap
I had bought a waist belt similar to this when I was pregnant. I had 2 slipped disks and I was worried about my pregnancy putting too much pressure on my back. I found this little gem and it was WONDERFUL after my cyst collapsed. Since there is excess blood or fluid in your abdomen your insides to feel icky (best I can explain it). I found that walking made everything move around and caused things to hurt and feel more uncomfortable inside. I put on my pregnancy belt and viola less icky. The belt restricted the movement of my internal organs or fluid and made it easier and less painful for me to walk or go up and down stairs. I put a link below because I found non-pregnancy ones for about $11. You probably don't already have one but they are worth the money especially if you get cysts often.

4.Eat Slowly or Eat Small Meals
I found that eating and drinking was also painful. I'm assuming that it was because my stomach was expanding and therefore had more irritation on it while it was getting larger? Who knows. All I know was that if I ate slower and in small meals throughout the day I felt less pain.
I know that these are only a few tips but I hope that they are helpful for you. I especially hope that they help to ease the pain for some of the unfortunate women of the world who have polycystic ovary syndrome and get cysts often. Let me know if you have figured out any other ways ease cyst pain. I'd love to share them!
