Sleep comes as the final event of the day. Parts of the locomotive system are exhausted at its maximum at that time after serving the human needs. Therefore pains and aches are more prevalent at that time
Causes. Most leg pain results from wear and tear, overuse, or injuries in joints or bones or in muscles, ligaments, tendons or other soft tissues. Some types of leg pain can be traced to problems in your lower spine. Leg pain can also be caused by blood clots, varicose veins or poor circulation.
We provide rest to our restless body at the end of the day ( just before sleeping) and hence we feel the pains which were already there the entire day.
