Recently diagnosed with hyperthyroidism?

I just received the results of a thyroid test, and it showed I have hyperthyroidism. My TSH was very low (0.004), my T4 was high (14.1) and my T3 was high (298). I haven't been able to get into an endocrinologist yet. What, exactly, do these kinds of levels indicate? Are they severe levels, or do they indicate something like Graves Disease? Also, I'm concerned about the treatments. I've heard horror stories about the meds, and I had a small reaction to iodine dye in a CT scan, so I don't know if RAI is an option.
I also have had almost no symptoms; in fact, I showed symptoms of HYPOthyroidism. I sweat very little, I've been having weight gain, my hair is thick, I'm sensitive to cold, not heat, heavy/long menstrual periods, constipation, hoarseness, muscle aches. I have no Graves symptoms. I do have breathing problems, but I smoke. My thyroid is enlarged.
Has anyone heard of being diagnosed with hyperthyroidism when most symptoms are opposite? Also, what can I expect from treatment?

I also suffer from depression, like hypothyroidism causes, but I also am a nervous twitchy person as well. Also, despite the weight gain, my appetite hasn't changed, in fact, my diet has improved because of it, as well as exercise, to no avail. No problems with nails, except that they're thin/weak, no myxedema, no clubbing of fingers. No signs of Graves' opthalmology except for occasional dry eyes and frequent blinking.

Hyperthyroidism is a condition caused by the effects of too much thyroid hormone on tissues of the body. Although there are several different causes of hyperthyroidism, most of the symptoms that patients experience are the same regardless of the cause (see the list of symptoms below). Because the body's metabolism is increased, patients often feel hotter than those around them and can slowly lose weight even though they may be eating more. The weight issue is confusing sometimes since some patients actually gain weight because of an increase in their appetite. Patients with hyperthyroidism usually experience fatigue at the end of the day, but have trouble sleeping. Trembling of the hands and a hard or irregular heartbeat (called palpitations) may develop. These individuals may become irritable and easily upset. When hyperthyroidism is severe, patients can suffer shortness of breath, chest pain, and muscle weakness. Usually the symptoms of hyperthyroidism are so gradual in their onset that patients don't realize the symptoms until they become more severe. This means the symptoms may continue for weeks or months before patients fully realize that they are sick. In older people, some or all of the typical symptoms of hyperthyroidism may be absent, and the patient may just lose weight or become depressed.

It seem as if you will be around for awhile. Hope this helps.
