Hyperthyroidism Neck Pain Pain In My Lower Legs?

Pain in my lower legs? - hyperthyroidism neck pain

I had such bad pain in my lower legs for about 3 days now. It hurts when I flex my feet, shins and calf pain almost all the time. I was very tired and irritable. I am also part of the neck and back pain, and the feeling that I can hear things in your neck.
I think my time will begin in about a week, but usually no pain in his leg. I'm also a little sneeze. I have hypothyroidism (in fact it could be hyperthyroidism, I can not remember which), but otherwise I'm very healthy.
If anyone knows what happened, I would like to know what you think. Thank you!
