I had a cyst aspirated ( ordered by Dr N Brooke of southamton hospital England)
It is a big mistake, it takes about 10 minutes and is extremely painful almost passing out type pain, I was pain free for 30 minute before it filled up again spinal fluid.
I also had surgery this year 19th of May. My surgeon Dr casey of London royal othopedic told me aspiration is a big mistake as it just causes un-needed pain and has the potential to burst the cyst and cause more issues if u plan to have surgery.
Sorry to scare you but I am currently going for damages with a solicitor due Dr Brooke's incompetence, please don't hesitate to message me.
On the plus side surgery did work for me, I am able to go to the toilet without a catheter or enemas.
