hand tingling and numbness

[autumnneuner]

I fell at work and landed pretty hard on my knee and right hand.I am having back pains,knee pain and what is driving me crazy is since the fall I have been having episodes of my hand feeling like it fell asleep (the tingling sensation)but it happens when in use also it goes numb...this didnt happen until I got injured at work.Does anyone know what it could possibly be?it obviously has something to do with the fall since I have never had any prior problems.Thanks for any suggestiong on what it might be or what could have caused it.

Hi, Thank you for your question. It seems that your hand tingling & numbness symptoms could be due to injury to a nerve, pressure on spinal or peripheral nerves (neuropathy), vitamin deficiency, lack of blood supply due to cholesterol plaque from atherosclerosis in the extremities, viral infection and use of certain medications.  In addition, atherosclerosis can also cause pain, numbness, and tingling while walking and they can also reduce blood supply and lead to numbness. Please consult your doctor to get all these possibilities evaluation in your case for further assessment. Hope this helps.

It could be a number of things which I wouldn't begin to guess.  

No images done?  (MRI, CT).  There should have been especially if it is work-related.
