Methylpred DP and back pain

Ok my doctor Gave this to me 1 cause its cheap and 2 cause I pulled some muscles in my back. well today is day 2 of taking the pills and I cant hardly sit. my hips hurt so bad its insane. im not sleeping cause of the pain and its not helping my back at all. Im very disappointed. cheaper isn't always better is it!
Ive had a headache ever since i started taking it! Im exhausted. and my back pain is getting worse, Im going to call my doctor tomorrow and hope that she will give me something better.

I am an insomniac and this medicine has caused it to get worse. I have not slept since I started taking it and I am so tired but just can't sleep. I have had nausea, constipation, back pain, burning eyes and pain in my knees. I can't sit with my legs bent without have awful pain in my knees and when I lay with them straight they fall asleep. Has anyone had this problem? My heart races more then usual.

Took 2, 6day packs 4mg for 2 ruptured discs causing crippling back pain. Could not walk much at all or stand straight. Im 37 years old male, have always avoided any meds if possible.
Results:
Back pain went away after 10 days, along with good chiropractor visits, cold pack treatments throught the day and lots of lying flat on my back wearing a brace provided by chiropractor.
Side Effects:
-Sleepy during day, difficult to sleep at night.
-Slightly blurred vision.
-Constipated at times and loose at times, small amounts blood in stool three times.
-Frequent trips to urinate with uneven flow all the time.
-Have had slight occurances of heartburn.
-One week after 12 days treatment was over the pain returned more and more and I started to peel on my face without being in the sun, without redness and I have been well hydrated.
-Maybe depressed but may also be caused from needing to cancel scuba diving trip due to condition.

Starting to take 6 day pack again for returning pain. Wish me luck...thanks
