Here is some info on hip flexor injuries to those who may be curious.
I am wasting no time and I started doing my rehab exercises on my right hip tonight! I kept my Theraband from when I injured my other hip flexor because technically I should be doing the exercises on a regular basis... oops...
It's interesting too... while I was looking for a site with example of the exercises I noticed several sites mentioned the importance of stretching and that stiff muscles can exacerbate this problem. It's funny I have decided recently to work on stretching more because typically I only stretch when I'm sore due to the fact that I loathe stretching... Yeah I know not good... But I am trying to do right by my body and I'm trying to grow to like stretching (LOL). Good thing too because I do NOT want to break the bone of my other hip! That is the goal: to avoid bone breakage.
Here are the best pictures I could find of the exercises I am doing and descriptions also:
