Hello and thanks for writing in
If you had not trauma in the past few days than this pain can be related to the spine problem or sciatica
. But these type of pain starts from the back and goes to the lower end of limb. The pain which started from the big toe is the pain if Gout
. You can check it by blood investigation of Uric acid. If it is increased than you have to get treatment for that.
Hope I have answered your query.
