Dear Christal,
WHile it is tough to be 100 % accurate without doing a physical examination, I would agree with your concern about a pinched nerve.
The cause of this pinched nerve could be a local condition like burisitis, OR sometimes even a lower spine abnormality like a compressed disc/ herniation etc.
What you require is a detailed neurological examination by a neurologist to ascertain the cause of your problem.
Please remember to accept the reply if you find it useful. A BONUS and a positive rating would be duly appreciated,
