Trap-Queen
Hi I was diagnosed with this today and I don't know much about it ive looked online but it's not very informative.
Does anyone have this? 
Do they get headaches that are caused by sneezing coughing laughing bending over like a sharp stabbing tension pain? 
After you were diagnosed did you get any pain relief without surgery if you did have surgery what was this like?
Thank you to anyone who replies x
