Hi !!
I have read through your problem ..I would advice you to do the gleuts stretch,hams steretch, quads stretsh with the piriformis stretch at night before you hit the sack ..
This would help you reduce the pain and stifness in the morning and your pain will definately go off .. just give yourself another 3 days time and keep stretching 3 times a day ..
1st set of stretch before you get off the bed to brush
2nd set in the noon
3rd set before you go off to sleep ..
You follow this and it would really help you ..
