Hi. I have hypothyroidism, paroxysmal atrial fibrillation, glaucoma and rheumatoid arthritis. I take medication/use eye drops for all of these conditions except for the RA, which has flared up badly recently. I'm also on Apixaban. Up until 2 years ago I was perfectly healthy and took nothing stronger than paracetamol occasionally. Now it feels as if I've suddenly reached my 'best before date'. I'm 64 and still as active as I can be - which is pretty active. I can't help wondering if there is a link between these conditions as they all seem to have flared up at the same time. Any thoughts? Also any thoughts on vitamin supplements? Throughout my life I've generally taken these but have stopped as I was worried about possible interactions with drugs.
