More women than men have FM but substantial numbers of men have it also. Be careful about subscribing symptoms to FM (or CFS) without having a doctor check them out - studies have shown that substantial numbers of CFS patients have undiagnosed ailments.
FM can cause all sorts of pain but it may not be causing your heel pain. You might want to check out a condition called plantar fasciitis that causes heel pain and can be treated. You can find out more about plantar fasciitis at
