Today I did some rearranging and messing in my tank and water change, was in there for about 3-4 hours, I had gloves on for most of it. About an hour after being in the tank, I started with what I thought was allergies, running nose, sneezing, watery eyes, it's been about five hours since symptoms started, and it's like I got the flu , chills and all, even having to use an inhaler. Took zertec and tylonal severe cold and flu.... If I still feel like this in the am I may call the doctor, anyone know what to tell him or has this happened to anyone before, or know how long it lasts?
