I was on Nexium for gastritis and I started taking sertraline. Around the same time that I started sertraline I started developing a lump in my throat but i thought it was because of the Nexium. I discontinued Nexium but I am still feeling the lump and now I get fluids come up my throat sometimes burning my air ways. I didn't have this before starting Nexium or sertraline. wanted to see if anybody else has had this? thanks. I am still taking sertraline 50 MG daily.
