Apparently, some of the disease's symptoms can return much later in life.
And, according to the Post-Polio League for Information and Outreach, it's important to know the symptoms because they won't go away on their own. The symptoms include: unaccustomed fatigue; joint and/or muscle pain; muscle weakness and/or loss of muscle use, and respiratory problems.
This condition isn't all that rare. According to the Post Polio Task Force, as many as 200,000 Americans may suffer from some or all post-polio symptoms.
If you experience any of these problems, you should contact your physician. There's also an Internet site dedicated to those who have had polio and may have problems with its aftereffects.
