Numbness???

Past couple days I have had numbness in certain parts of my body. It's starting to freak me out and I don't have insurance to just go check it out. So maybe you guys can shed a little light on whats been going on.

First the numbness started in my fingers and hands then after a while the numbness would fade... Then randomly the numbness would come back in my fingers and hands I also got numb on my chin and bottom lip. That lasted about a day... off and on numb..

The next day- gradually I felt numbness randomly almost in waves (it comes and goes)in my fingers and hands along with my chin and bottom lip again and as the day went on the numbness traveled up my arms to my elbows almost to my arm pits again random numbness coming and going...

Any thoughts???
