My shoulder was really sore last night but I managed to get some sleep thanks to a kidney destroying amount of naproxen sodium. While yesterday, the only visible damage was road rash on the back of my shoulder, today the front was black and blue. Its appearance will probably get worse, but the discomfort is lessening. I did an easy 5K around noon, just to make sure I didn't have any long lasting damage. That was encouraging. Right now I have the unabraided parts of my shoulder slathered with a generic version of Vick's Vapo-Rub. It seems to help. So I can detox from the NSAIDs.
