I guess I got it from spin class. It came on suddenly and it hurt to sit. Now it constantly hurts. I am post menopausal and I keep reading things that it could be caused by lack of estrogen. I use an estrogen suppository but according to the pharmacy it is a low dose of estrogen. I was an avid exerciser up until 4 years ago. Now I may walk 2 times per week. I did have a Pudendal nerve injection in a hospital and my pain was gone for 12 hours. Because of that the nerve doctor did Cyroablation of my Pudendal nerve which did not help. I have taken Botox injections and taken many medications. I started taking lyrica and I thought it worked a little but after 2 months I can’t tell. The lyrica makes me dizzy and have a numb head. In my last MRI which was for nerves my nerves appeared to look ok and nothing stood out. I will have regular MRI mid June. At this point my GYN is sending me to a pain doctor. I guess I am glad I did not get this when I was younger.
