Hi, it does sound like cysts on ovary to me. When you say the pain lasted half an hour that was the same with mine. I have never heard of having endo on just one side before so I suspect you have it on both. I would ask to see the gyno and get a scan done. Hope you are better soon xx

I have had excruciating pain on and off in my right hand side which they thought was appendicitis.

I have 1 cyst.

It’s not normal to be in that level of pain.

Stick to your guns as the saying goes and go back to your GP, change GP if you need to. It’s you that’s in pain, nobody else and it’s your right to know what’s going on with your body 💕x

I had the same thing but had ignored the infrequent quick stabbing pains i got on that side over the last year.

I've also had one previous surgery with endo removed but no cysts.

Ended up having the same pains you describe now, one sided and very often, pulling sensation too.

Ultrasound has shown a 5.6cm endometrioma cyst on my ovary so i'd say yours sounds similar!

That sounds nasty! Have you had to get it removed?

Just had my ultrasound this evening - got a cyst! He's giving it a month to reduce and then he'll remove it.. also discovered my pill is still making me ovulate, so is literally doing nothing. just so frustrated...
