Lateral Meniscus Pain

[nmarman]

It's u likely to be meniscal tear because of mode of injury and that you can run thought it. Locking and giving way are clear indicators of meniscal damage.

More likely it's runners knee caused by tight ITB: follow a protocol of foam Rolling on ITB 5 rolls 4 times a day for 3 weeks and ice knee where it hurts twice daily.
You can get a ITB strap and wear it everyday during week one then just during Higgs and runs.

No doubt you also have a fall arch or run in what it's termed a valgus fashion so have a look for some running orthotics - these help in 75% of knee pain cases.
Hope that helps,
