I haven't exercised for three weeks because I was concentrating on my return to work. So because I have been improving since my dental work (ie. No headaches or neuralgia) I did a three mile walk up and down a very steep hill as soon as I got up and have no reaction, headache or anything, I don't even feel tired. It seems ever so strange not having any head pressure at all! I just wonder if the tide in now turning! I think I will stick with long walks for a while and then maybe go to the gym for bike, crosstrainer and walking on the treadmill in future. I don't want to do too much though in case I set myself back with starting back at work as well, and the Cymbalta has reduced my symptoms so this could be giving a false impression. Only time will tell, when and how much exercise I can do in the gym again.
