I've been feeling pretty rough since i packed in smoking 3 years ago. The main symptom has been tendonitis, however my hair has been falling out, i've been making mistakes due to lack of concentration at work, i have a constant reflux cough, breathlesness, over 2 stone weight gain, carb & caffiene cravings. However, tiredness has been my least troublesome symptom. Though i have been going to bed earlier and earlier, and catching myself napping on the sofa unexpectedly in the evening. But it was enough to make me ask for a thyroid test. Blood tests have shown TSH level of 5.87. However T4 is 18.9. I have requested a free T3 test twice and both times lab have not actioned the request. My ferritin is only 30 and my b12 only 222. Both at the very low end of normal which i'm told is also hypothyroid related. My doc has told me there's nothing more he can do, but i'm only 42 and i'm hobbling round like an old lady. Where do i go from here? Has anyone been in this situation? Any advice mych appreciated as i've been made to feel like a hypochondriac.
