I am sensitive to a lot of things and my symtoms range from hor,red soles of feet, to all over rash, quick heartbeat. Anyone know of insulin both long and quick without this preservative. Banging head against brick wall with gp and specialist. Have many other health probs and am on oxcycontin, fluxetine, baclofen to name a few....... :!:
