It could be. I am thinking it is, mostly because the pain I have had is only on one side, which is consistent with shingles. They are both made worse by intense exercise... of course I don't hear that (hands over ears). Interestingly, both are treated with low doses of Amyltriptiline (sp), which I took for a couple of months in 2008. It worked, but when I started gaining weight, I went off of it. Plus, it makes you sleepy, so you have to take it at night, early enough to get enough time to sleep. I goto bed later now, so it would be hard. But, it broke the cycle.
We shall see. The only exercise i did today was a 12 minute warm up on the treadmill and the stuff the PT has me doing. I felt a little worse after getting off of the treadmill, but I often feel worse in the morning and then it disappears as the day goes on. I really want to go nordic skiing tomorrow, so I am headed off to finish the paper I am working on.
