I was on Levonquin for pseudomonas. I had to be taken off as I began getting joint pain in my elbow's. The doc took me off it right away. I am sorry to say the only other treatment for the lpsudeomonas if a pic line. So i had one for 3 weeks and that took care of the psudomonas,,,,,,,for now. I can never go on the levoquin again because of this. I still have the joint pain 5 months later. It may never go away. Good luck and take care and keep me posted on what comes next.
