Hello everyone, I'm new to ehealth and I'm an 83 year old woman diagnosed with multi nodular goiter in June 04 when I was merely 77. Always fit, played crochet, drove around holidayed and lived a wonderful independent life. I was prescribed Neo-Mercazole (Carbimazole) 5mg daily. Didn't do much so had RAI treatment, doctor wanted 2 doses but it made me so sick I only had the one. Went back on Neo-Mercazole 5mg and been on it ever since. Ever since I was diagnosed I've been weak and tired with no energy to do anything any more. And now some 5 years later I'm worse than ever, and have had 2 mini strokes in the meantime and just found out that I have Atrial Fibrillation. I thought great they've found the problem after all this time, but now I've been researching and Thyroid problems can bring on AF. My Cardiologist seems to think I probably had it all along and it possibly caused the strokes. I'm now on Warfarin and Metroprolol. Along with these I'm on Avapro, Natrilix, Caduet and Caltrate. I feel like a pill bottle rattling around. Bottom line is I'm worse than ever now, so weak, can't drag myself from the bed to the bathroom, can't shower without having to flop back onto the bed straight after, also have a terrible raspy cough getting worse and worse by the day, feels like its in the chest and hurts a little now. I've had a husky voice ever since being diagnosed in 2004 but now its worse. I'd like to know if I should still be on this Neo-Mercazole after 5 years, could it be that making me weak and tired all the time? And what would happen if I went off it just to see if it is that making me weak and tired. Would that hurt me for a week or so? Bloods always come back in normal range. I'm at my wits end because now I'm wondering if I may have something else now with this raspy cough. I'd appreciate any responses. Regards.
