Are these normal TSH and Free thyroxine levels?

I have hypothyroidism, was diagnosed about 5 years ago. I've just done a test after about a year and these were my lab results. Are they normal?

T.S.H 2.20 miu/ml

Free thyroxine 1.69 ng/dl

I'm very doubtful because of late, I've gained about 15kgs just out of nowhere and I've also started to have muscle cramps all over and my hair started falling badly about 6 months ago The weight gain I can put down to excessive eating. I've also noticed that my neck- round about where the thyroid gland is, is slighlty more swollen looking. I remember this was one of the first signs whn I was first diagnosed.
