My husband has MS. He tried the ABC drugs (avonex, betaseron, copaxone) and they didn't work. He had to many side effects from them all.
He is on a test right now of testerone. He is a guinea pig for it. But it seems to be working.
How long have you been diagnosed? My hubby has been diagnosed for 6 years now. He suffered symptoms for many years though. He is now not working and we are in the process of trying to get dis/ssi. But they don't really recognize MS and he is only 39.
Email me if you need to . Would be glad to talk with you.
There is another new drug out called Tysabri. It's an IV medication that you receive at the hospital.
