How to avoid pain in joint while running fast ?

i would suggest you get it looked at before continuing to run. You do not want to do untold damage. Does pain last long once you have finished running & if so do you ice it & elevate to help reduce any inflamation.
Difficult to say if anybody else would have the dsame sotrt of pain as there are many different reasons for that pain.
I tore my Hamstring Tendon last year & had to have 3-4months without any running. I can now run but have to run with pain but I also have the same pain when walking & the pain does not get any worse when I run so am ok.
As I said earlier. get it checked out first then i would take it easy for a while then startrunning again with gentle runs of 15- 20 mins increasing gradually back up to 20 - 30 then further if you wish.
I,m 71 & run I'm 71 & run3/4 times a week covering up to 26km a week

I would think you put more force/weight on your joints whilst running than you do walking I think you should seek medical advise firstly and then Look at your shoes and see if having your shoes fitted to your feet might help

Knees wear out.
People who run a great deal quite often have knee problems later in life.
So you should take great care of your knees and preferably not run if it hurts.

Once very important thing is to use proper running shoes designed for your particular running style.
This can help cushion your feet, ankles, knees and hips when you run.
This in turn could keep you injury free for longer.

I have had to give up running because of knee joint pain; however that was only about 3 years ago and I am 67.
I can still walk, but if I walk too energetically (long fast strides) I get knee pain as well.
Cycling seems O.K. but for the occasional little niggle.

We feel pain for a reason - it is our body telling us something is wrong. It needs investigating.

Do not forget to get a doctor to check its not something medical before changing shoes
