Hi Goggi, I don't take Orencia but I do have Menieres. I had it for years quite badly. It disappeared for about 12 years and has suddenly reappeared along with the tinnitus that accompanies it. I would discuss it with your rheumatologist to see if there is a correlation between its return and the Orencia. Mine said no to it being brought on by Cimzia or RA. Would be interesting to see if anyone else has the same. By the way, mine seems to be worse in heavy atmospheric weather like thunderstorms etc.
Think I won't take any more Orencia until then as my head is like it is full of cotton wool today and hearing very affected but at least the nausea and vomiting is gone (for now)!
