normal tsh with positive tsi

[maiden51]

For 12 years since a hysterectomy I have had several hyper and then hypo episodes.  Endo keeps telling me it's going to burn itself out.  TSH levels drop usually to .6 and go up to 1.8.  Just recently found out I have TSI levels of 93. Does Graves cause these ups and downs, and is there anything I can do to help myself, since doctors seem to think there is no problems.  I have several of the hyper symptoms,  along with a extremely positive family with thyroid problems.

The levels are normal, there is no evidence of thyroid disease at this point -- the TSI is normal - does not look like Graves.

Thyroid symptoms are so non-specific, with a lot of other health conditions having the same symptoms as thyroid, it is very difficult to distinguish where the symptoms are coming from or which health conditions are the cause.
Symptoms could be from your hysterectomy throwing you into menopause. Menopause symptom share some of thyroid symptoms, as well as a lot of other health conditions. Women have been know to suffer menopause symptoms way up in their 70's.  None of the thyroid hormone medications or drugs are a 100 percent cure-all for symptoms, so you might have to treat each symptom separately from each other.
Levels are the prevailing diagnose of Graves'/thyroid. Your levels are good, and as long as they are within Labs range, treatment might not be warranted per your doctor. There are many reasons for levels to fluctuate and, will or can be different even from time of day to time of night, (i.e. early AM). A person can be (more) hyper at one part of the day/night to where being treated could throw them into "med. induced" thyroid which could cause havoc to health.
Diagnose or treatments is not done by antibodies alone  and antibody presence or absence does not change the diagnosis of thyroid (which is based on serum TSH measurements) or the expected efficacy of treatment. People with other autoimmune disorders such as Sjögren syndrome, lupus, rheumatoid arthritis, and pernicious anemia, and in people who have  no evidence of disease, are sometimes positive for antibodies, so that is why thyroid levels are the prevailing diagnose, and antibody test are just to confirm.
Family having thyroid problems doesn't necessarily mean another family member will, however, it is a just cause for testing on a regular bases for just incase you show up thyroid in the future.

Continuous Good Thyroid Health.
