Hopeful,
I use compound cream, Gabapentin 5 %. Lidocaine, 10 % and Compket 10 %.-- I put it spearingly on top of each foot, just over the joint, and a little on each wrists.-- I can use it 3 times daily, but usually I use it twice daily. I try to use it between doses of Lyrica, because the cream can be powerful.

Hopeful, is your underlying condition Arthritis? Mine is Vasculitis and Arthritis. The rheumatologist has me on Full dose of Methatrexate. The doc had switched me to Cellcept for a while, but the jointpain became worse, so I am back on Methatrexate.
I hear you have received IVGG? Has this been helping for you?
I am getting so desperate for solution. My doc mentioned to start Rituxan, but so far I am waiting to have some more tests like right now, a temporal artery biopsy.
Good luck to you.
