Hi i was diagnosed with anUnderactive Thyroid 2 years ago now i was initially placed on 25mcg of Levothyroxin which went up in 3 months to 50mcg, i then suffered with irregular and racing heart beat, panic attacks and a feeling of Doom all the time.

My GP referred me to the Specialist who told me to come of the Levothyroxin and see how it goes.

Left this for 2 months and the Heavy periods started again calle GP and was placed on 25mcg, which i am still on today and still suffering with the same thing chest pains heavy and irregular periods skippy heartbeat and all the above .

Does anyone else feel the same would love to know im not going mad

    In response to your query I too quite a while ago experienced racing heart beat at night whilst sleeping and panic attacks... I thought I was having a heart attack! until it happened several times after that over the next few months.. again I went to my GP and blood test came back normal. My attacks only seem to last one or two nights and then stop. I take my medication regularly every morning at the same time so cannot explain why it happens.

    Hi Terri

    You must be my twin! I was diagnosed a year ago - I moved house and found a new doctor who took one look at me and asked if i'd had a thyroid reading. When it came back she said I was "grossly" hypo and she said I would feel like a different person after 6 WEEKS on 25 mcg levothyroxine!!! Ha Ha Ha! She's a lovely doctor and I do not blame her for not knowing everything about this disease (how can a doctor know everything about every illness?) but she could not have been more wrong. I suffer from flooding periods, which are now constant and am consequently very anaemic. After years of seeing umpteen different gynae's and getting nowhere, I am having microwave ablation next week, which i am assured should stop the heavy bleeding. Before diagnosis, I used to sleep all the time and barely move in my sleep. I now thrash around the bed and usually get kicked out! I have a thudding heart rate, twitching and muscle spasms and anxiety dreams. I've always suffered from depression and was put on Prozac about 8 months ago, which has just been changed to Citalopram as doc thinks prozac might be cause of anxiety. Not sure. I'm now up to 125mcg levo and do certainly feel different from before diagnosis, but this is a really long journey and I do feel for you. My partner thinks I am fat, lazy and a moaner, which does not help. I feel feelings of doom and despair a lot and at the moment am also extremeley angry. Itchy skin, sore joints, stiff feet and ankles, feel cold most of the time...... the list is endless! I'm 46 and feel ancient. Why are thyroid problems so poorly understood. Keep on trucking, you're not alone Jan x
