Hello.........I am being treated for essential blepharospasm. I am getting botox treatments and also my Dr. Prescribed amitriptyline for headaches and anxiety. There is a warning about sore throats with this medicine. I have had a sore throat for 2 weeks . I have been taking this medicine for about 4 weeks. I haven't talked to my Dr. About the sore throat because I have also at the same time had alot of allergy and sinus problems. Is the sore throat really something to worry about and if so, why. Thanks....Rene
