Hi. I Have Had A Hyperthyroid Condition For 11 Years.

Hi. I have had a hyperthyroid condition for 11 years. Recently, I have had a tooth removed due to a poor root canal I had to have a titanium implant. I now have hyperthyroidism .081 is my reading, off the chart! I did have bone grafting done as well and a new crown. Could any of this be causing my hyperthyroidism? Also, my T-3 and T-4 reading are within range, so I really don't understand why my THS is .081. I still feel like I'm having hypothyroid issues.......My doctor still has me taking synthroid. He just lowered the dose. I am not certain I should take this. Maybe, the synthroid is causing my hyperthyroidism? We just changed this as well from levoxyl about 9 months ago....I've only had two readings just recently. My first was 0.03 and my second is .081 as of now.........Thanks for your advice.
