I have a stiff neck when I move my head to either side. I am 80 but I m in good shape as I work out at the gym and do yoga once a week. However, I the afternoon I recline In bed and watch tv for about 4 hours as I get up at 5:30 am and stay pretty active for about 7 hours. I m also an artist and sitting for a couple of hours concentraing on a painting can sometimes produce a stiff neck. This is something that has come up In The last month and it s not getting better or worse?!
