My daughter is 12 and runs cross-country. She runs approx 5 miles per day 5 days a week. An MRI shows she has posterior tibial tendinitis caused by an ill fitting pair of running shoes. But it also shows that every bone in her foot is bruised. Obviously it is bilateral. A few questions
Hello, It will not affect the height and stature of the kid.  It is just a transient condition and will settle by itself. As of now, you can use analgesics/anti-inflammatory combination like diclofenac/serratiopeptidase for symptomatic relief. Apply ice packs for faster recovery. Keep in mind that strict bed rest is the treatment of choice for this benign condition. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
