how can i prevent my joint pain?

Go to an orthopedist.

I think you should need to consult a doctor for this.

In the interim, you can try applying 'deep heat' (its a tubed cream)..
I have a shattered cartilage and it helps sometimes with that, its particularly good for back pain.

Cod liver oil capsules taken daily will alleviate the issue eventually.
Sometimes athletes sprays are good.

It can be worse, if it suddenly jerks and the pain is highly acute, it can indicate a nerve issue, I have this and strangely it appears once every few years.

Across assorted areas, I find Chinese medicines are great for fine tuning the body and spirit, even helping with some minor to intermediate problems, whilst Western medicine can help more with very deep seated issues. (drug testing scenarios aside, which might as well be 'drink the lighter green part of the pond and see')

Hi
In my opinion you had better consult a doctor very immediately.Otherwise it will result some bad situation.
Thanks.
