编辑同志:我今年53岁,出现夜间背痛的症状已经10多年了。每当到了后半夜,我后背的中上部就会出现难以忍受的疼痛,常会将我疼醒。我若是在白天过于劳累或换个地方睡觉,晚上就不会出现背疼。我曾去医院进行骨科检查及心电图、心脏彩超、动态心电监测等心内科检查,但没有发现任何异常。请问,我患的什么病,应如何治疗?青岛许×× Editor’s Comrade: I am 53 years old this year and I have had back pain for more than 10 years. Whenever I got into the middle of the night, there was an unbearable pain in the middle and upper part of my back, often waking me up. If I am too tired during the day or go to bed, I will not feel back pain at night. I went to the hospital for orthopedic examination and electrocardiogram, echocardiography, Holter monitoring and other cardiology examinations, but did not find any abnormalities. Excuse me, what diseases do I suffer, how to treat? Qingdao Xu × ×
