I have post traumatic arthritis in my hip form a fracture afew years ago. Uaually it just aches a little, but I've been on my feet alot more than usual at my new job, on bad shoes. It's also been getting nippy out, which makes it worse. Last night I had ALOT of pain in my hip, and in aweird spot. It is very sensitive if it's touched. It's not so bad today, however, it still hurts if i touch that spot. Is it maybe a strain?
