That is interesting Ken (as well as quite funny!). The trouble is this problem crept up on me so I have no idea when it started - or even when I properly noticed. I was on injections of methotrexate with Hydroxichloraquine tablets for two years so I decided it must be drug related but it's never come back. I think it's a bit of a coincidence that I also have numbness and parasthesia and dizziness and the lack of smell (and taste too to a lesser extent). But I'm sort of hoping the removal of my gallstone with longstanding stones might help. They say that autoimmune diseases are usually connected closely with the gut so this doesn't seem like an impossible idea. Mat x
