Severe muscle pain when I wake up?

5 days ago I rapidly developed the symptoms of flu, namely fever, headache, severe muscle pains, exhaustion etc. I spent a couple of days unable to move from my bed, sweated and shivered and ate very little. I did not go to the doctor because I understand that this virus is highly contagious and I have kept well hydrated. I have limited my medication to paracetamol and ibuprofen.

After four days I started to feel a little better. My temperature is now normal and I don't have a headache. When I went to bed, the-night-before-last I was feeling quite positive because the muscle pains had also gone.

When I woke up yesterday morning I experienced pain that I have never felt before; severe, tearing, crippling pains in every muscle (and I mean EVERY muscle) of my body. It took me 30 minutes to get out of bed, I was very worried, my first thought was that I had been poisoned. I stayed out of bed all day yesterday and I kept moving all day (I have three children) and by last night the muscle pains had gone completely, I was feeling positive again when I went to bed. I had no temperature, no pains, no headache, my appetite was back.

At two o'clock this morning I woke up with the same severe muscle pains all over my body. The pain is excruciating, almost unbearable, and it has taken me an hour to get myself out of bed, slide downstairs (because my legs are two painful to bend) and write this email.

Can this really be attributed to the Flu? Can the muscle pain on its own really be this bad? And only after I have been to sleep? I thought sleep was the time I would recover, not the other way round, now I'm scared to go back to bed.

Or could this be something else?

Please help me.

You must be in terrible pain! I think you should phone your GP's office asap. They will be able to advise you, if you are still contagious or not. 

Did  you get an answer from your physician to your pain?  This has been happening to me (exactly as you explained, but without the flu) for the past two weeks or so.  But, only if I wake up during the night.  It was 2:44 AM this time and I was unable to go back to sleep until 5:AM.  Due to all the pain meds prescribed for my Fibromyalgia and Chronic Fatigue. I have quite a few, but no help with this pain or either way too slow respondimg.  They do not help as in a pain crisis like these.when I have these nocturnal attacks,  It is horrible. but I am, glad to see I am not crazy.  So sorry about your pain; I did not mean that I was glad you hurt.  Please respond, I need to know.  I do not want to go to sleep or wake up.  THANK YOU so very, very much. Our insurance is a mess over here as you have probably heard.  No one in the average walk of life here can go see any doctor they want anymore. To go see a Rheumatoogist or any other kind of specialist we must first see our primary physician and then they refer us.  It is costing us and our insurance companies so much extra money and time to get to the right specialist  Again thank you for any info you can give me..  

This happened to me 2 nights ago ago, but do not have the Flu or any other sickness...woke up after a great sleep, and every single muscle in my body was in SEVERE Pain...never experienced anything like this...
