Hi Doc I am 45 year old, last few months once in a while i am getting a severe pain on my coccyx when I am in deep sleep and disturb my sleep for 5 minuts its happened 5 time last one year , now frequency reduced. ...I went to the Orthopedic Doc and consulte with him he saying no problems, but i am really confused what is? Because i am having no problem with sitting or playing during day time why this happens only in the night?
