As someone who started on doxycycline and then moved to rifampicin, I can tell you that it doesn't have nearly as much anti-inflammatory effect as doxy, but remember that you were also taking azithromycin, which does. If you have a busy period coming up, you did well to restart to stop lingering worry, but I feel sure that in the end everything will right itself, including the tingling! If you read Bobbie's posting, he tried out minocycline for a day at his doctors suggestion and ended up flat on his back for a few hours. Not surprisingly he is going back to doxy. I suppose that all one can do is keep in mind that if abx had no effect on MS, then they could be taken with impunity but no improvement either!
An Itinerary in Light and Shadow Completed Dr Charles Stratton / Dr David Wheldon abx regime for aggressive secondary progressive MS in June 2007, after four years. Still improving with no relapses since starting. Can't run but can paint all day.
