Welcome advantage,
You've come to a good place there are some great people here who know how support you. What you discribe is how it started for me, but from me feet up. My feet felt like they were going to break in two across the instep. It has since moved to my hip right side only. (it was both my feet) The only thing that helped me was to go on steriods for alittle bit. I think it was like 10 days can't be sure, but that sounds right. I've never done them for more than 10 days.
Hip pain is still with me I was trying to stay away from the riods for a year do to the weight gain.
I hope this helps. I'm sure the others will be along be for long with more.
take care of you.
