[|Human|] I have had lower back pain for 3 weeks.  Saw a physcian assistant last week. Gave me exercises pulling knee to chest, bridging, ect.. Been taking ibuphren once or twice a day.  Been appling heat at night.  The pain is not as bad but still there.  I have noticed getting more stiff when getting up from sitting.  Im 41 and not overweight.  What could be causing the pain?  Should I see my primary care doctor or another doctor?  Would a MRI be helpful?  Thanks
[|AI|]  Hi, From history it seems that there might be having degenerative changes in your lower spines giving this pinched nerve pressure symptoms. There might be having some stiffness of back muscles as well. Go for x-ray lower vertebrae for osteoarthritis. Avoid sedentary lifestyle. Go for daily physical exercise like walking, swimming etc. Go for back extension exercises daily. Take calcium, vitamin A and D supplements. Ok and take care.
