Numbness and pain in left leg and foot (two middle toes)

Doctor, I am a 35 year old female that has had numbness and pain in my left leg and foot for over a month now.
I don’t have health insurance (won’t until next month) but I’m afraid that it may be something serious and my not going to the doctor due to the expense could cause me more trouble.
What could this be from?
Pinched nerve perhaps?
I do have back problems and I’ve had problems near my cervical spine for years.
Please advise.
Oh, I also wake up in the mornings with numbness in my scalp, fingers and arm.
