I'm experiencing some kind of reaction to Chelation therapy. My left leg started going numb. My legs never went numb before. Yesterday I noticed some lumps on my back. I had been taking 'Cardio Renew' for a couple of weeks, but I stopped because I don't know why this is happening. I don't take anything else so I know its from the chelation. Can anyone shed some light on this? Is it a detox reaction? Thanks in advance.
