Are her feet inverted/everted?
One foot or both?
Whatโs going on @ knees/hips?
History of injury, etc???
Itโs hard to say what is going on with your client from your description, but Iโll share what my daughter went thru โ maybe it will helpโฆ
My teenage daughter runs track and strained her left lateral calf & tested positive for lateral leg strain (peroneus longus). She also felt pain in her ankle & pain in the attachment at the base of her pinky toe bone (5th metatarsal). She had a difficult time training and missed most of the season.
In trying to figure out what was causing the problem, (in addition to going to our Dr to check for a stress fracture, yadda, yadda, yadda) we went to the local running shop & had them assess her gait while walking and running we found out that she inverts her ankles. They fitted her with appropriate running shoes & it has made a world of difference. About 3 months later she was just beginning to have the same pain, so back to the shoe store & discovered she needed a new pair of shoes. Weโve been able to stay on top of it since.
The moral of the story for me was, the proper shoes make a world of difference and replace them regularly - every couple of months if need be.
When I have a client who inverts their ankles, their lateral calf muscles are strained, stretched out & weakened โ hence the trigger points. These are the muscles that will need to be strengthened.
The tight muscles causing the inverted ankle are Extensor Hallicus Longus, Flexor Digitorum Longus, Flexor Hallicus Longus & Tibialis Anterior & especially Tibialis Posterior. These are the muscles to get in and stretch/open up/loosen up. To get into the posterior tib, try reaching in behind the tibia, approach from medial and work to warm up/loosen up behind the shin bone (hope you can get the visual). Go easy in here โ not uncommon to hear my client say โohh, I didnโt know it was so tight thereโ. Of course you want to work the whole lower leg โ gastrocs, soleus and lateral leg as well as the foot, upper leg & hips โ thereโs usually stuff going on there too. But see what you can find when you go digging behind the medial aspect of the tibia.

Hope this helps
