Synthroid and sooo

i've been on synthroid for 9 years. started at some low dose and gradually went up to112 mg. get extreme itching all day everyday if i don't take allegra for that.not a rash just itching. that doesn't bother me as much as the fatique. every joint in my body aches all the time. sure there are better days but fo rthe most part it's bad. tried physical therapy and chiripratic care but no avail. they ended my sessions. my legs get sooo weak and my feet burn lower back really aches. sometimes muscle cramps. i'm very negative towards my loving family and it hurts me to do so. can't seem to keep upbeat. soo tired all the time.
is it the syntroid? i used to be very energenic and a doer. now i have spurts of activity in the morning , but then i just can't get motivated. help me any suggestions?

I am 23 and found out just a month ago that I had graves disease, hyperthyroidism and a cold nodule that they couldn't determine if it was begning or not so I just had my thyroid removed last week and I started synthroid a few days laterl. I've noticed that I'm a little
shaky, i thought maybe it was from my parathyroid glands not producing enough calcium but even though my calcium levels have gone up i'm not visibly shaky just feel shaky,
I also don't want to sleep I feel like I have more energy but at the same time i've been weepy. Is this normal?
I really haven't had a chance to ajust to any of this it's all been happening sooo fast.
