Question
Cynthia,
       It doesn't help to stretch the hip flexors, they tend to shorten. Are there anything else I can do?PLEASE help  

Answer
I'm sorry, I've given you my best ideas.  I presume physcial therapy would help, or possibly acupuncture. It is difficult to get more specific without actually examining you.

It sounds like you need to actually see someone that specializes in sports injuries.
