Levaquin B Cell Lymphoma, Agent Orange Exposure, Gamma Globulin, Oxygen Bottle, Side Effects of Drugs

Ran into friend at grocery store with mystery illness. Docs attribute it to Agent Orange exposure. Been at death's doorstep for a year. Hands were extremely cold and has little energy. Showed up one day at golf course with oxygen bottle! Asked him if he had taken Levaquin. Unfortunately had. Docs again fail to link antibiotic exposure to his ailments.
I wonder how many illnesses and deaths this poison has caused? Why does the FDA allow this crap? Do you people realize that the average person is clueless about the side effects of drugs like this. Put total confidence and their well being in the hands of ignorant docs and profit crazed drug companies.
Ignorant oncologist failed to link my dad's symptoms to Levaquin, instead attributed them to b-cell lymphoma which just happened to suddenly appear. Rituxan and numerous other drugs (Heparin, Lasix, Gamma globulin, Tylenol, antibiotics, Insulin, steroids, Flowmax, etc.) was too much. A fiasco, people think he died of lymphoma. Was walking three miles a day before taking Levaquin, for an undiagnosed lung infection.
