Why am I not surprised, P??
I threw out my back recently and have been in absolute agony all weekend. Today, dosed heavily on ibuprofen and pre-loaded from a ebsom salt bath, DH & I went to the D.C. Car show to look at new cars. About as anti- bike as you can get but we did get plenty of walking in.
Now, I've got the TENS on my back and will spend the rest of the evening on the couch.
