They also test my T3 and T4 and both are right in the middle of proper range. I can not remember the exact number. My Dr is sending me to another endo because this has happened more than once. I don't understand how the T3 and T4 are good and the TSH is creeping. The problem is the more i read the more confused i get. My dr said even though I am taking the 137 (now150 mcg) My body is not registering that it's there. I also have had a sinus infection for 2 weeks and of course the asthma kicked in....I just feel like I have been kicked hard the last couple of weeks and nothing is working. I am on my second round of antibiotics for the sinus infection, they upped the synthroid to the 1.5mg and steroids for the asthma...I am from Canada, and our medical system runs a little different. The waiting list for these specialists are also forever. I have had 5 endos in the past and the ones that seem to understand see me once or twice and retire or a few have passed on (unfortunately before they finish giving me a diagnosis) The last one I saw said I needed to see the heart specialist which in turn said I am too young for this...... Most of the time I feel good. I don't understand what throws me off so bad...If I knew I could quit doing it and maybe this merry go round would stop. I don't know if it makes a difference but I also take B-12 shots.
