siatica pain that keeps coming back!

Hello, I HAVE BEEN CRYING ALL DAY FROM THIS HORRIBLE PAIN ON MY RIGHT SIDE DOWN MY BUTTOCK INTO MY LEG. I HAD BROKEN MY ANKLE ABOUT 10YRS AGO, IT WAS NEVER OPERATED ON AND I REMAINED WITH A SLIGHT LIMP. WE MOVED DOWN TO FLORIDA FROM N.Y. BECAUSE OF FINANCIAL PROBLEMS. I HAVE ALWAYS GONE TO THE CHIROPRACTOR BUT HAVE NOT INSURANCE AND LIVE ON S.S. I PURCHASED A TEMPROPETIC MATTRESS ABOUT 8 YRS AGO AND NEVER HAD A BACKACH AGAIN, UNTIL RECENTLY. I HAVE BEEN TAKING TYLINOL EXTRA STRENGTH EVERY 8 HRS. I DON’T KNOW WHAT ELSE TO DO FOR MYSELF. ANY HELP IS APPRECIATED. THANKS RITA
