You Hello, My Name Is Susie. In 1953 At Ten

You hello, my name is Susie. In 1953 at ten years of age, i had spinal and bulber polio. Now at age 75, they are saying I have post polio syndrome, but no answers as to how or why nor what to do about it if any thing. I have noticed over the past few years, weaknesses and ive been an avid exerciser and swimmer for a good 65 years. All of a sudden , I have no energy, nor desire to do anything, and I hurt. You mean I'm going to go through all this again? What can I do to prevent this? Are there any answers?
There is no ìnformation that I can find,. You can reach me at : YYYY@YYYY
Thank you
