I really hate wake up in the morning. It's cold and it is very painful to wake up, even if is not cold. I've searched on Google about ways to reduce pain, but I didn't found anyway. Can you give me any solution?
I wake up because I need to go to work.
Even if I go to sleep earlier the same happens every day.
What type of pain are you getting? Is it pain in your shoulder from laying on it? In my case, it is because I need to drop some weight (about 30 lbs or so). This can also apply to back/neck pain, esp. if you notice increased pain the more you sleep in.
Do you have a regular exercise routine? That may help (although the pain will probably increase when you start a routine -- make sure you don't over do it). Doing some stretching after exercise will help with this. Also a hot bath before bed to relax the muscles.
If you have joint pain, such as feeling pain in every bone in your feet, that goes away with a hot shower (or after getting some movement going), this is due to lack of lubrication in the joints. Some people have had luck with Glucosamine -- that's something I'm going to try shortly.
Oh, and again, if the pain seems to increase with more hours in bed, and you can't find the right mattress, then you could try breaking your sleep into two 4-hour shifts -- sleep when you get home from work, then get up at midnight, and go back to sleep between 2 and 6.
Finally, some pain is normal, but may feel a lot worse if there is any depression issues going on. But real bad pain (absent of any depression) isn't really normal -- you should talk to a doctor about it.
