an ENT doctor has suggested chemical cautery for my sinus and allergy problem. All he would tell me is that it s a simple procedure - done once/month for 3 months, then follow up in 4 months ... then once or twice a year thereafter. After a some online research, I m really scared to have this done. I ve heard all about the scabs, infection, soar throat from the chemicals, coughing, drainage and weeks of severe pain. People are just letting the ENT doctor do the procedure with these strong chemicals that can effect you for life. At least this is what I m reading online.
