In case you don't know, some studies have shown a possible link between Arava and sensory neuropathy. My rheumy took me off Arava a few days ago so it's early days yet but fingers crossed. I can barely walk now and it seems if the Arava connection applies the longer it goes the less chance of a fix.
An advanced Google search for "Arava neuropathy" will turn up the limited studies done so far. May not apply to everyone, of course, but tingling etc is one of the symptoms of neuropathy which is serious.
Thanks for this info dessy. It is something we should all be aware of.
