The entire downfall of my health began with a neurotoxic reaction to the antibiotic, Levaquin, in early 2010. It damaged the triceps tendon in my right arm and triggered an overall toxic reaction to my immune, muscular and autonomic systems. I saw specialists for a year and a half, took many supplements, did PT, etc, and finally improved. However, in 2012 I got mono from EBV and never recovered. My naturopath is convinced that the Levaquin messed up my system making me susceptible to mono and many other health problems. I have been officially diagnosed with CFS by several MD's but many are still unaware of the connection to Levaquin (in my own case.) It has an official name now "Fluoroquinolone Toxicity Syndrome" and I am including a link of a letter written by Dr. Jay Cohen to the Senate re: this issue. Here is the link: http://www.medicationsense.com/articles/2014/letter.php My question for the board is: are there others here who were negatively affected by Levaquin or other FQ antibiotics (cipro, floxin, avelox, etc) who later went on to develop ME/CFS? I am very appreciative of any feedback on this issue and thank you for reading.
