Shelley,
I'll have to ask about those particular viruses as I don't know. I also suffer with ON but its due to my neck. These conditions are the pitts

.
Let us know how the meds work for you as you go on. The direct nerve blocks for the ON worked for me for a little while, but they are temporary. The initial anesthetic shot is heaven while it lasts. I got some prolonged relief after a second shot with steroids, but it also wore off so right now I'm in limbo there. I've never had any blocks for TN, but I don't know if you're referring to that too, or what. Maybe I'm just over tired and things aren't real clear right now.
Take care

EE
