the return of the sinus headache

Up  since 4 a.m. with a doozy of a sinus headache. Yesterday I felt good enough to engage my stretching routine for the first time in months. But plenty of neuropathy reminds me that I am still in the woods. Also, ventured out into the 20 degree F weather to do a couple errands, but just enough to go from car to store, etc. Third variable: I practiced some. I was very careful not to push on the practice side, just some easy long tones and low, in-the-staff notes. One or more of these is responsible for this damn headache, I am sure. I didn't think it was as vicious as it now seems to be so I just took two aspirins. I may have to bump up to the codeine in another hour if things don't improve. Scans tomorrow. I seem to recall being in the middle of a prior round of headaches during the last set of scans. Hope this is not a repeat.
