My husband and I were both diagnosed with Hypo in the last couple years. We hadn't gone to the Dr much before that & both had always explained our symptoms as other things. I was sub-clinical at first, meaning my TSH was low but my T3 & T4 were in the normal range. Because I was having hypo symptoms they decided to treat and check my levels every 3 months. They had to up my dosage at the last visit. I can definitely tell a difference on the new dosage because I was freaking out at the dumbest things right before.
There is a lot of good information online, but if you don't understand something make a list and ask your Dr. Good luck!
