Abnormal Thyroid Test results

I recently had a routine blood test for my annual physical come back abnormal. My doctor is concerned about it and has referred me to an endocrinologist. Will see the endo in 2 weeks.
Here are the findings so far:
TSH   .27
Free T4   1.29
Free T3    381
Thyroid Scan/ Uptake    3.3% at 6 hours-Radiologist states that this is in the hypothyroid range and the thyroid gland is relatively small.
My symptoms are more hypo such as constipation, fatigue, weakness, i have gained a few pounds and find that i am craving sweets more than usual. Have difficulty losing weight with diet and exercise. I also have a fairly consistent mild headache. I do have allergy sinus problems so don't know how to differentiate between that and possible pituitary tumor, etc.
WHAT MIGHT THE PROBLEM BE? Secondary Hypothyroidism, Pituitary Adenoma, or nothing at all???

THANKS

The TSH is slightly low -- not likely significant --the 3.3% 6h uptake is low -- combining these suggests a transient silent thyroiditis which is likely to resolve on its own.  

The radiologist should NOT say "hypothyroid range" -- only the blood tests are used to see if a patient is hyper or hypo -- the iodine uptake is only used to determine why.

most likely the other symptoms are not thyroid related.
