Occasionally, (about 4 times over the past year) while I am sleeping, most of my muscles will tighten so tight that they will hurt for several days afterwards. At the same time that is happening I will end up having large amounts of mucus come out my of mouth. The most recent time this happened my lips turned a very dark purple as well. Does any one know what is going on?
ps If it helps I am a 30 year old male.
