My mother ( 55) was put into the hospital last week with swelling of the tounge and throat. They thought it was a reaction to Robaxin( back med) and put her on a flush and meds to bring her adrenalin down. Her blood pressure etc was all fine. She came home that night..only to go back again with the same thing.. and the 2nd dr there said if the swelling didn;t go down they would have to put a tube down her throat. It did, but they admit her.. and she was in for 4 days.. In that time.. it happened again.. but nothing they did could tell them what was causing it? She said she would get a funny feeling and then like there was something in her throat and she had a hard time swallowing... they ( 4 drs by now) didnt think it was a reaction to the back medication.. but not sure what? They sent her home with an epi pen.. and medication in case she got the feeling of it happening again and mentioned it may be anexity. She has never.. had anexity... everyday stress but not anexity.. any thoughs on what may be causing this???
