Hi There, I Would Like To Enquire About Knee Pain.

Hi there, I would like to enquire about knee pain.
About the pain:

First noticed in summer 2020

Highest pain I’ve experienced was 4/10.

When moving them, I can feel clicking. This is on both sides and not audible.

Sometimes my ankles and similar areas have a sharp pain, around 6/10. This tends to go within a few minutes.

Notice occasional pain in my feet, around the big toe area. Gets worse when moving them 4/10

Get occasional leg cramps when in bed, approx 1 in 3 months. These are incredibly uncomfortable.

Used to fall over at least once a week in spring/summer 2017. This is because I have a brain injury and had to re-learn how to walk. My knees look heavily bruised because of this. Haven’t fallen over in at least a year.

No family history I am aware of of knee pain.

About me:
24
Female
BMI of 22.62
Never been overweight
Walk twice a day

I was wondering whether anybody could tell me if this pain is something to be concerned about? I spoke to my GP but they just brushed it off and gave me no diagnosis.
