More accu-torture

Sunday was the worst treatment yet: the vibrations were very strong and instead of the soothing numbness at the end, there were spastic intervals of irregular vibrating current, as if there were power surges going through the building every so often. :_( The acunpuncturist also mentioned that while my tendon is healing (I certainly feel that too), he is not certain what's going on with my knee (which feels as stiff as before) and if I'm not better by the next appointment, I may have to get an MRI. All this time I thought Chinese medicine was a safe alternative (I hate taking drugs, etc.) but in the end even centuries-old therapy has to rely on Western technology. What did they do before the MRI?
