Speaking of this, I had runner’s knee on my right knee for 2-3 weeks last month. Resting didn’t help much until I prescribe myself the jump squat workout 150 sets back to back last week and my runner’s knee fade away.
My right knee also not good liao
Can give leg side raises (standing form) a try as well. No harm in trying. For runners, many cases is weak gluteus medius as a pretty big root cause, fix this and majority of the cases can prevent the issue already. When it gets better, do it conscientiously and add in resistance bands. It works for me, it works fo rmy senior father.
Can also hoot the hamstring and anterior tibialis, no harm also and can be supplemented, any sort of exercises for those would do, just youtube search.
Not sure about the jump squat workout but heck if it works for Kuudere, can try that as well.
Also useful would be NSAIDs if pain is particularly bad, it pays to reset the inflammation present (stiffness, pain at the extremes of ROM range of motion). Reduce the inflammation to as low as possible, then start the rehab with any strengthening exercises. But of coz Jeremy1 cannot take lah.....coz of GI issues.
Personally i find arcoxia (or any generic etoricoxib) to be the best for such pains....however this arcoxia might be of higher risk in some areas like congestive heart failure vs other NSAIDs etc.....so naturally of coz need to consult docs first if you have any other comorbidities before starting anything.
Personally i find it to be pretty solid vs naproxen sodium / ibuprofen and also my other family members be it mine or my in-laws (PF pain lah.....rotator cuff lah......so many cases for so many years)
If got swelling or stiffness, cold treatment of the joint might help.
Light exercises/movement is good, but do not gun through the pain if it starts acting up again. Need to pull back / reset again before continuing
