IT Band Problems - Acute Pain With Siting And Standing

IT band problems - acute pain with siting and standing from a sitting position - goes away quickly - worse in the mornings - gets less sever after exercise and end of the day. Symptoms stated suddenly on Dec 24 and stayed the same since then. No trauma - don't know why it started. I am 71 years old - in good shape and active. Thanks for whatever you can offer. Larry
