Still feeling dizzy after taking Levothyroxine for two days at 50 mcg.?

I feel like I have vertigo cause my head feels really heavy and I get dizzy alot. Could this be from the medicine? The doctor wanted me to try it to see if it would help my symptoms because he suspected that and candida which I have been treating. My liver had been hurting the first day I took the levothyroxine and I had been treating candida for about two months to the day when I took the Levothyroxine for the first time. Could I be getting dizzy due to my liver being in bad shape, because it still hurts today? Btw, the doctor did do tests and said my TSH levels, T3, and T4 levels were ok but, he said that even though they are fine it could still be my thyroid so he suggested me trying them. Can taking the medicine when you don't need it cause your levels to increase and not lower? I mean I have been suffering with bad symptoms for a long time, but I just can't deal with this vertigo.
