Grinding sound from joints, should i be concerned?

You obviously have some knee problem that got worse by the stress. I have knee problems too (don't recall the name) and one time I hurt it pretty bad jumping to grab some Mardi Gras beads, but it got better after a few days.

Get your shit diagnosed, if it hurts it's wrong. At least you'll find out dos and don'ts about it

What do I do I can't afford to go to the doctor's about it.
Like, things I could try before going to the doctor's?

Assuming it's nothing crazy your body should be able to heal itself given time. rest, put your feet up and ice it if it's hot painful or swollen. Try not to do anything to make it worse. If you can't afford to see a doctor look for a free clinic in your area. Like the other anon said it sounds like you have some sort of pre existing condition considering that you're young, not overweight, and can't walk more than a mile without your knees hurting.

Don't walk.

Also, if you're flat footed it could be because of that. It could be making your knee not track right.

Start saving to see a doctor.

I'm the anon you quoted

For the time being, do ice if it's been less than 48h and hot water if it's been more. Avoid doing whatever move it is that make it happen for a while. My problem got better within the first week, so if it take too long to get it better, you'll HAVE to go to the doctor since you could have snapped something and require surgery or some other care.

If it heals on its own, start doing stretches and work out with the directions of a professional to strengthen the muscles around the knee, which will help give it better support. Also obviously avoid high impact exercises like basketball or running. I never use the threadmill, always go for the elliptical since it doesn't have impact.
