....hope you get some helpful comments and ones that will help you get back to how you felt before. 2016 I was given a Quinolone drug, Norflox, for bladder infection - read the pharmacy sheet with the prescription and said to spouse i dont really want to take these but did, for obvious reaons.... didnt want to rock the boat. Two weeks after got up and walked across bedroom carpet and could feel every fibre in carpet on bare feet, odd, went to make breakfast and fintgers and hands tinling. Lower legs feet lower arms hands... checked for Magnesium and told to see fam. dr. when returned from vaction -when I did he got a big black medical book off shelt and said: says here side effects headache and nausea! OMG. I had 3 pages of info from Pharmacy with the pills warning of this and careful using in those over 65 etc etc.. but I dare not speak up. Anyway, I ended up leaving that Dr. I should have shown him the BLACK BOX WARNING on the pills - never had seen that before and the pharmacist just said to spouse tell her not to drink milk for 2 hours... Then on top of it all, looked up on Internet and discovered the lot number being dispensed at Pharmacy was RECALLED by Health Canada the year before but would not say why. The Pharmacy technicain said he couldnt tell if the pills were from the current lot being dispensed but he told chief Pharmacist and I heard her say we have to recall pills. (guess they didnt get notification recalled year before). Long story short Peripheral neuropathy in thos areas still and sort of began the beginning of the end for me regarding health and who knows what illnesses followed were because of not only this Quinolone drug but the fact I probably took recalled lot of pills! Thankfully,, coping with the P.N. and refused meds for it as have other issues... but as years go on feet are worse and more symptoms..... Yes I do believe one pill can cause problems, proving it is another issues. (Recently Trimethoprim another antibiotic and 2 days after have sort of "visual snow.". Was it the meds??? Best of luck, J.
