You should inquire with your doctor. Without more information, it is difficult to suggest a diagnosis. I had one patient with a similar complaint after she took a Doxycycline antibiotic capsule without water right before lying down for bed. My patients are advised to take the capsule with a glass of water and stay upright for at least 20 minutes to allow the capsule to dissolve in the stomach and not the esophagus. When the capsule does this, it can be very irritating, as you are describing. The good news is that these symptoms were temporary. Hope this helps and good luck to you. For more information on this and similar topics, I recommend a plastic surgery Q&A book like "The Scoop On Breasts: A Plastic Surgeon Busts the Myths." Good luck to you.
