I have been on pain meds for a while for chronic back pain and nerve damage in my right thigh. Given KVK Tech pain meds by my pharmacy and it was downhill from there. The meds were by far the worst I ever had! First of all they did not alleviate not one bit of pain I experience. Second of all the meds made me feel like I had to barf and I experienced withdrawal symptoms after one single dose. I don't know what they put in this crap but it needs to be taken off the market! My Doctor destroyed and replaced them but what about folks who can't get around and are given this crap. I will be reaching out to my Congressman, two U.S. Senators and the BBB about this incident! This company has so many complaints and bad reviews that it doesn't make sense. Stay Away, Stay Away, Stay Away!
