I have tenderness in my left temple always. My vision on my left side gets out of whack (hazy like - dry eye) too. Exercise helps. Try to remember to keep your shoulders down. Your body is carrying stress in your upper back. You don't realize it, but your shoulders are probably shrugged up from tension (maybe not, but was the case for me). I still have my bad days, but nothing like it once was. Good luck to you.
