I am trying to define the reason for a sour, metallic odor coming through my skin in the last 8 months, it has gradually increased and my wife & I cannot seem to isolate it. I take a number of medications for sleep, Ibuprofen PM as well as a time released Gabapentin for neurologic discomfort, Tizanidine for sleep, Trazedone for sleep, but have used cheap shampoos & body cleansers (although these have been used for years) I have had labs done on blood work and they show liver & kidney function as fine. Did not do a metal test for increases in various possible metal buildup. Have not been able to isolate any particular food but not the best at eating fruits & veggies, have taken to drinking chlorella & charcoal tabs to address this. We are baffled.
