... sore and raw throat and now ulcers have formed.. I have been put on every med you can imagine and antibiotics.. (Prilosec, diflucan, zpac, augmentin, niastatin gargle, singulair, ect).. Nothing relieves my symptoms.. I take Flecanide 2x a day.. Even Ibuprofen gives me absolutely no relief.. It's like I'm having an allergic reaction.. Anyone experience this with Flecanide?
