It is called being cold. Unless you are in a hot place, then you might be sick. But otherwise you don't describe anything that won't happen when you are very cold. Hands go numb, the eyes get cold enough to water, and shivering is a natural reaction the body has when it gets very cold. It is the bodies way of trying to make motion to heat itself back up.
PAIN - diffuse musculoskeletal pain and fatigue. The syndrome is defined by the presence of musculoskeletal tender points on physical examination. Pain is often described as aching, burning, throbbing, gnawing, shooting &/or tingling. It can be localized, generalized, can feel like muscle spasms and can be scattered throughout the body. It may be migratory, with pain presenting in one or more areas on one day and other areas on another day. Pain is often experienced very quickly after any repetitive movement - even something as simple as holding arms up to brush or comb hair etc.
Due to the lack of Stage 4 sleep, muscle repair does not occur properly and therefore muscles take longer to heal and regenerate after micro injuries or trauma, as is experienced by everyone in day to day life. That or your just cold and sick.
If it is constantly happening, make an appointment to see a doctor. Rightnow, take a couple acetaminophen or ibuprofen. Have warm clothing on, and when you are lying down underneath the blanket, make sure your arms and hands are in a position to where you are not cutting off blood circulation. Relax them.
