Hi 
Hope this message finds you in good health.
I have gone through your complaints and understand your concern.
U seem to have compressed a 
nerve in the back somewhere that might be causing 
radiating pain in those regions.Possibility of a 
lumbar disc prolapse  should be kept in mind.
I suggest you get an Xray as well as an 
MRI to find out the exact cause.
Physiotherapy,analgesics,anti-inflammatory drugs,lumbar traction ,infra red therapy should help.in difficult cases,using a lumbosacral belt should be helpful.
Avoid surgery as far as possible.If at all its needed,get it done endoscopically.
Nothing to worry about.     
I hope your question has been answered.
If you have any follow-up queries,feel free to consult me anytime.
Thanks,Take care,God bless.
