I have been training for the 2 day breast cancer walk for a few weeks now and have noticed some new hip pain. I'm going to my doc in a few weeks for a physical and will probably ask her about it then because I know hip pain can be hard to diagnose. I did want to see if there was any advice in the meantime from you super-knowledgeable athletes.
The pain is on the outside of my hip, very localized, at the widest part of my right hip only. The pain is kind of sharp, not really aching, hurts the most when I take a step with my right leg, and is strong enough to really irritate me after about 4-5 miles. It generally stops not too long after I stop walking. I have brand new shoes which feel amazing on (and no more shin splints! yay!), so I don't think it is the shoes. I don't seem to have the problem when I am cycling and haven't even noticed it when I run, but I've only run once since this problem started. I have been doing some hip stretches and I think it might be helping a bit - mainly pigeon and bound angle pose.
I'm guessing it has something to do with my IT Band but I'm also a bit concerned about my actual skeletal structure. When I check my hip height in the mirror there is a huge difference, my right hip is a good 1-1.5 inches lower than my left hip. I don't know if this is just normal and everyone has a degree of it, though.
I'm going to go look into a foam roller today maybe. Thanks!
