Hi, may I answer your health queries right now ? Please type your query here...My husband had a stent put in on July 9th 2010, 2 weeks to the day later, he started having ulcers in his mouth, I mean serious ulcers, at one point he could not even swallow his own syliva. He has been in the hospital twice with this, they have tested him for about everything. Every time he get s off steroids, these sores come back, he s lost about 42 lbs. Could he be allergic to the stent??? All the doctors tell me it has nothing to do with the stent??? Something has to be causing it.
