Could be sciatica. Could also be something with the SI joint or hip flexors, or even hamstring. I highly recommend chiropractic care for such things. Especially one who doesn't just do back/neck adjustment but does whole body muscle work. My chiro is amazing. I messed up my back/hip just before xmas and it was my psoas. Some deep tissue work (which required him digging into my pelvis to get to the psaos from the front, yikes!) and some at home stretches he gave and after a few visits I was back to 100%.

Have had great improvement or total elimination of: migraines, bloating/distention, heartburn, cystic acne, canker sores, bleeding gums, eczema on elbows, dry skin and scalp, muscle cramps, PMS, hair loss, heart palpitations, fatigue. I'm amazed.
