I was diagnosed with an e. coli infection. I began taking Levoquin. Suddenly I had terrible, crippling joint pain, tendonitis in the back of one leg, and a fever of between 99 and 101. I live in Nicaragua, and chikungunya is rampant where I live. My doctor suggested that I had unfortunately contracted chiky at the same time as my e. coli infection, and she said I should continue with the levoquin. After three days of Levoquin, I was unable to walk or use my hands/thumbs. The pain was unbearable - and unfortunately consistent with both chikungunya AND levoquin damage. I stopped taking the levoquin. two days later I have no joint pain and my temp is normal.
