I have had an under active thyroid since I was 16, now 56. I suffer the symptoms of, utter complete tiredness, foggy mind, memory issues, migraine, sometimes hot sometimes cold, dry skin, overweight, hair loss, ezcema, asthma, IBS and headaches. At weekends, when not working I can sleep for 11 hours straight and I have to get at least 9 hours sleep on a working day. I have been on T4 since the beginning and T3 since about the age of 26. My doc, although sympathetic has stopped prescribing T3 because of the price. A private prescription is approximately £325 per month. Last week the consultant at the hospital agreed that I needed the T3 and is writing to my doctor about this but it will depend on whether or not the surgery can afford it. Is there anyone else in this position that could offer me some advice about what to do next, do I just have to live with it and consider myself fortunate that I haven't got something more serious wrong with me. I have a very healthy diet and walk everyday but I have been exhausted for 40 years.
