My Left Thigh is Numb

the other day when i was doing RDl’s on the up part i could feel some strings in my left thigh stretching. days later now my left thigh is numb in the exact same area i felt the stretching. its been like this for a few days and sometimes it burns a little bit.

i had this problem before and then it went away and now it has come back

what is it?

can anyone help me out? it hurts a little now. its a burning pain.

might be a nerve issue, go to doctor if unable to cope with pain.
