Pain

I learned how to treat my frozen shoulder from a young physical therapist.
The first time I saw him he said "This is bad. You have to be prepared for some pain during the treatment" in exactly the same way as DAIGO speaks. He told me to lie on my back. He then held my arm and forced it up. First slowly to check the movable limit and then push it gradually beyond the limit. It pained. I moaned. But he seemed not to notice it. He kept pushing further. Although I grew up being told that a man should not easily say "ouch" and I have been following the teaching, I could not help letting it out. He ignored my ouch and kept pushing. It was agonizing. It was terrible. He was right it was certainly painful.
After the treatment my arm felt light. Again it may be the matter of comparison but I really felt my arm got better. From that time on I didn't care much about the pain in my shoulder. The pain was there but I realized that pain itself was no serious thing. We tend to think that pain is a sign of something ominous that is impending. But once we know it is something we have to endure in a healing process, the pain loses its significance. This thought made me feel much better. The sense of pain also has a mental aspect.
Since then I have been treating my shoulder by myself following the way the young therapist did to me. It is still painful. Now I can raise my arm up to near my ear. I feel much better though the pain still disturbs my sleep.
