Cindy, I do not know what RSDis. Symtoms of throat closing can be related to an allergic reaction- perhaps to food, medicine or environmental. Notice what you have eaten or are around when this happens. Swelling of the throat can also interfer with breathing. I know my mom and I take a benadryl- an over the counter allergy pill- when we have the "throat feeling". Let me know what RSD is.
