Waking up sore - muscle tension?

Hi,
I'm experiencing a lot of upper back pain at the moment. My GP says it's muscle tension due to anxiety. I'm totally convinced by that diagnosis apart from the fact that I wake up stiff and sore. Does anyone else with muscle tension experience aching that's worse on waking?

100%. Even though I don't 'suffer' with anxiety any more, my life remains extremely stressful and this will not change in the foreseeable. I wake up every morning feeling like I can barely walk and needing a good nights sleep.

I find meditation before bed helps.
