Numbness in limbs

Over the past few month I have been having a lot of lower back pain.  I think it is related to how I sleep.  I sleep on my stomach and I feel like my lower back is forced into an un-natural v shaped position.  I have to sleep with a pillow under my hips.  Recently I have been experiencing weakness and shaking in my quad muscles and arms.   Almost like I need to eat but that does not help.   Could this be related to my lower back pain?  Would could it be?  I am a little worried.

Hi,
How are you feeling?
Your symptoms appear to be of radicular pain radiating to thighs and quad muscles.
In the lumbosacral spine, radicular symptoms are caused by an intervertebral disc bulge, protrusion, extrusion, or sequestration that compresses and inflames a nerve root in approximately 98% of all cases. Other causes of radicular symptoms emanating from the lumbosacral spine include disc osteophytes, a buckled ligamentum flavum, zygapophysial (Z)-joint hypertrophy, and other causes of lumbosacral spinal stenosis.
The other reason could be dehydration, vitamin deficiency or malnutrition causing such a generalized symptom.
I think you can consult a PCP and an orthopaedician for further diagnosis and management.
Keep me posted.
Bye.
