Question: Hi I've been on metronidazole for nearly 6 weeks and took my last tablet 12 days ago. After being off them for 5 days I started to experience pain in my calf below the knee. This got worse over the last 5 days and as I was on holiday at the time I just though I'd pulled a muscle. I flew home from XXXXXXX Lanka but walked about a lot and pain was still there. Yesterday I saw a nurse at my GP's who did a D Diner test for DVT and it came back as positive for blood clotting. I'm now on anticoagulant injections until Monday when the hospital can do a scan. Today I've started feeling pain in my other leg and a slight pain in my arm. I am wondering if this could be my body getting rid of the metronidazole?? I had a lot of side affects whilst taking it including headache, lose of appetite, confusion, memory lose, nausea to name a few. Have read that metronidazole can cause blood clots so am wondering. I was on the tablets due To having dental surgery including. Extractions, implants, bone grafts, stitches with an infection in the jaw as well. I am airlinecabin crew so use to flying and am always active. I'm 41 yrs old with no medical history in my family of clots.
