I thought of that the other day and searched it. It's in clinical trials right now, and would love to try it once it's out. I just hope they don't have to go too deep to do it, wimpy me - I swear it feels like it's in my bones. Got tired of trying to suck it up, so I'm going to up my morphine to 10mg twice a day. It's still not a very high dose, but it sure helps, and helps the rest of my bod too. Thinking an extended release morphine might be better for me, but not sure if my gp will be on board with that - we shall see.
Sure hope your friend gets help from the botox.
