I just wanted to introduce myself. Am 52 and currently seeing a chiropractor due to having spasms in my lower back, caused by an injury at the beginning of the year whilst being very stubborn moving big boxes I shouldn't have moved! Between the ages of 13 and 15 I had sarcoma of the pubic bone, but kept defying the doctors and have led a normal life. The chiropractor has advised me that my sacrumilleac ...sorry I don't know how to spell it... has been out of joint due to standing incorrectly since I was young. Recently I have been getting terrible burning and stabbing pains in my groin area on the side where I had all my surgery long ago ... got to be honest, am concerned in case it could come back. They told me when I was young that the form of sarcoma I had couldn't return, but it kept on even after radiotherapy etc ... just felt this could be a safe place to get this off my chest! Thank you
