Without  additional information, TSH does not mean a lot.  It is an indication that you could be hyperthyroid.  Have you been tested for the biologically active thyroid hormones, which are Free T4 and Free T3?  Are you taking any thyroid medication?  If so, what type and what daily dosage?

Most important please tell us about any symptoms you have.
