Advair HFA and old husband

My 48-year-old husband began using Advair December 2003 and was amazed at how it helped his asthma. But then he started having other problems: high blood pressure, weight gain, muscle aches and weakness (he struggled getting up after just sitting down), and the blisters/bleeding/inflamed gums throughout his mouth. After a couple of months, I found this site and he discontinued using Advair. His blood pressure went back to normal in three days, the muscle aches disappeared, but we are still fighting with his mouth problems. He has been to the dentist; who referred him to a specialist. The specialist has given him numerous mouth washes, and two prescriptions. Nothing is working. Any advice would be greatly appreciated.
