most of the knee trouble that i've had has been under the patella, and has been helped by stretching out my tight i.t. band using a foam roller on the outside of the thigh. if the problem is tendinitis, that's inflammation, and the usual treatment is a couple of days' rest and anti-inflammatory meds, like ibuprofen, before easing back into activity. idk about any existing medical conditions she may have; if there are any, especially other meds that could contraindicate nsaid usage, she should probably have it looked at by a professional.
