I am experiencing constant aching in right hip. worsens at times especially during running.

Need an evaluation: In a female runner, I often say that hip pain is a stress fracture until proven otherwise. Thus, you need a specialist evaluation. Other possibilities include a labral tear in the hip joint, hip flexor/gluteus medius or minimus tendonitis, bursitis, etc. Referred pain from the S-I joint or the lumbar spine are possibilities. Stop running until you get more answers.
