Hi Mark and welcome to the group! So sorry you have to add yet another one to your 'resume'.

Being diagnosed in 1990, I'm now promoted to SPMS and use a 'chair'. Also have fibromyalgia and deal with the severe daily pain like you. So far I haven't found anything that touches the pain except general anesthesia!! I'm thinking about trying Lyrica (nerve pain) -- have you tried that one?

Like Cherie, I'm also on LDN, but haven't seen the same results. It does help some with the bladder issues and fatigue. That's the only thing I take for my ms since everything else had intolerable side effects.

Sorry I can't be of help in the meds department, but maybe it will be of some comfort knowing you're not alone. Please keep us informed if you find that "magic pill". This pain is really taking a toll on my life and probably yours too.

Take care.......Judy
