Mind and body works in tandem

When the mental tension is uncontrollable, pain killers or sedative have to be used.

I agree. Stress and emotional problems may cause a lot of physical ailments.

I would hope people realize how close muscle tension is related to mental tension, but a lot probably don’t. Tension headaches come to mind especially. My uncle suffered from them for years, and when he couldn’t seem to get ahold of his stress he saw a massage therapist who recommended putting very warm rocks (like pool rocks) on the back of his head and neck. I think a heating pad would work just as well to dissipate the tension though. After that, he no longer had to use muscle relaxers. Of course, I don’t want to put everyone in the same scenario. Some people have health conditions that cause involuntary muscle spasms, and we know that can’t be fixed by mental strength, although I know it always helps when dealing with any illness.

Tension and worry could cause a lot of physical ailments.

I am very good at discerning this. I always hated taking pills and look for alternative ways to ease pain. I have developed a very high tolerance for pain because of it and rarely ever complain of pain. The nurses and technicians at the hospital wouldn't believe me when I told them my wrist was broken. I sat calmly as they pokes and prodded at my broken wrist and they were convinced that I had only sprained it because..."If it was broken you'd be in much more pain than your exhibit." ...And then they Xrayed it. Yup. It's broken.
