[Concern] My right forearm hurts

I had a car accident some time ago.

I was just quietly waiting in the political lane... then a taxi suddenly sped up from behind!!!!

 

It was incredible.. At that time, my left arm hurt, so I received treatment and was cured..

 

My right arm hurts now.

 

It's not really the upper part to call it a shoulder... I think it's more accurate to call it the forearm.

 

The area about half a thumb below the shoulder line hurts.

 

It hurts even when I stay still, it hurts when I walk around... even when I massage it, it still hurts...

 

I usually don't work and have never lifted anything heavy.

 

I really wonder why I'm hurting...

 

Will it get better if I just leave it alone..?
