TSH level little high. Heal naturally?

I am 32 year old male. I had hyperthyroidism in 2018 and it went away after a month of medication. Since March 2020 I feel fatigued and cold during day, at times I feel feverish. I don't get much physical pain or headache etc as I began to excercise in July 2020 with long distance running etc. Since Dec 2020 I started having dizzi spells of 3-4 seconds once in a week or 2 weeks while working or while passing stools or sometimes during a long walk. I got my blood tests done. -2.48) CBC - all within range Blood Sugar fasting - 110 Blood Sugar PP - 100 Echo and TMT test all fine with 81% target heart rate achieved. Free T3 Serum - 3.09 pg/ml (normal range 1.7-4) Free T4 Serum - 1.29 ng/dl (normal range .77 TSH - 7.2 uU/ml Should I go for medication or let it heal naturally?
