I am having reaction to Doxycycline. Terrible cramping in esophogeal area, especially when I eat or drink anything! Was prescribed for bronchitis, and the coughing has just about quit altogether. Should I go to see After Hours docs at my usual clinic tomorrow as pain is no fun! When I have called to tell my doc, I got advice from phone nurses. They said to not take Doxy for a day and then finish the last two. I am not going to make this worse. Feels like an ulcer. I will get skinny at this rate! But these cramps are sorta affecting my breathing. Not interfering with it, and I am 82 yr. old female.
