I think you can to the right board for help...sounds typical of a thyroid problem! If you had half your thyroid removed, I might guess you need some thyroid replacement. You need blood work for FT4, FT3 and TSH to start. Many doctors only test TSH, but insist on the frees (F) as well as those are the actual hormones the body uses to give you health and energy. All the symptoms you listed are typical of someone who needs replacement. If you are already on replacement, than I suggest you may need more.
I also have a partially functioning thyroid for a different reason than yours, but my "previous" doctor said the left over thyroid could handle all the care my body needed...he was wrong and I got many symptoms. I am now on synthroid and doing better than before. If you get the blood lab don't settle for the doctor telling you you are in the "normal" range. Everyone here will tell you "normal" numbers are highly specific to the individual within that range...and it really DOES make a difference in how you feel. By law, you can get the results of your lab test and the ranges and if you post them here we can give you some ideas about where to go from there. Hope this helps...you CAN get better! :) Pixiek
