I hurt my back 2 months ago. The next morning i had rt foot and ankle numbness. In the past week had a knot come up on side of right leg. my doctor ordered an ultrasound to check for blood clot and it was negative.(the blood work was also negative)Back really dosen't bother me anymore. Just every once in a while when bending over. After i hurt my back went to chiropractor for several weeks. He did xrays and said the last disk in my back was pressed up against my tailbone and my rt hip had shifted. After my back was better he sent me to the foot doctor who said i had a cracked bone in my foot and put me in a soft boot. Started having alot of pain and went to er and they said my foot was not cracked to quit wearing boot. If you have any idea what this could be please inform me. I have pains up the bottom of my leg that alson come and go and some swelling during the day but goes down at night.
