Synthroid and deficient

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?

Hi everyone,
I have been on synthroid for eight years, it has not right for me. I started a combined T3 T4 medication a year ago and that made a great difference. I have now stopped all T4 and am taking T3 only in the form of Cytome, this leaves me feeling more alert, clear head, more energy and I am only on this for a week! You have to introduce the medication gradually, suddenly changing and taking the full dose all at once is a shock on the system, I break the tablets and take them over the day. I have to day taken a full tablet for the first time. I intend to take the medication spread over the day as T3 needs to be taken this way, unless you get a slow release form and this I have not come across, as yet. To be honest to ask the Dr for htis might just push him toot far!! I am grateful to have had the co operation of the Dr to try this T3 on its own, other Drs might have resisted. The body needs T3 to make T4, so it makes sense that we supply what we are deficient in, as opposed to giving the body the end product. I have read that there is a chance that the body will adjust with the T3 and start producing its own and then we can cut back on our medication and eventually stop. Thyroid medication has an effect on the heart, just as hypothyroidism has a negative effect on the heart. Taking too much synthroid can case severe heart trouble, the aim should be to take as little as possible but to take enoght to feel well. I personally will not take synthroid again. I found armour which is the combined tablet a much improvement and now I feel the popsitive effects of having no T4. I will keep monitoring andif I feel it necessary I will take some T4 again but to be honest I know I need to regularily monitor my blood test having tests for T$ and T3 and also free T3s. Take your body temperature every two or three hours a day and if your are consistenty below normal then this is a sign that your need T3. My body temperature is never normal always very low and no amount of T4 affects this. T3 is gradually increasing the temperature.
Hope this helps some folk.
