I've been taking doxycycline (100mg, twice a day) after a meal for Lyme for about two weeks now. So far my stomach has been pretty good, got a little nauseaous a few times but not too bad. The main problem I've been having is a tingling feeling in my hands, arms, feet, legs and sometimes my lips (almost like I had novacaine six hours ago). It feels like the blood circulation is poor, if I get up and move around the tingling goes away. At night I've been having trouble getting comfortable due to this, feels like my arms are falling asleep. Can anyone tell me how long this will last after I finish the doxy? I have about two weeks left. Thanks!
