I am in my last two days (maybe three) of a two-week trip to the West Coast. Got a Russel saddle installed last Tuesday and it is just fine-no posterior pain at all. Truly all day comfort. But my back! I get this pain after about an hour of riding between my shoulder blades. It stays with me all the time on the bike. I can stretch it somewhat for some relief, but it comes back shortly. When I get off it goes away. Any advice? How about the usual pain relievers, aspirin, Advil, Ibuprofam? Which works best for muscular pain like this? If it weren't for this and a weak battery, I would be thoroughly enjoying my ride.
