Question Summary:
Am I entitled to this personal injury claim?

Question Detail:

Am I entitled to this personal injury claim?
 
I was involved in an accident where the other driver crashed into me from behind and I suffered a head injury to which I was examined at hospital the very same day. I was told at hospital that if I experience numbness in the arms, I should come back to hospital. They did advise me to take pain killers if I experience soreness which they said I most likely will.
The next day I suffered from sore neck and back for a day or two. After several weeks, a company called me to say that I was entitled to personal injury claim. They stated that they will claim for injuries that are ongoing. I do suffer now and again with arm numbness  but I'm not sure if this is related to the accident as I had been experiencing numbness before. I also experienced shoulder pain but again I do not know if this was related to he accident.
I don't want to claim this money that I'm not entitled to but the company is adamant that I am entitled to this money.
Should I proceed with this claim or not.

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
If the numbness of the arm and shoulder pain which you used to suffer before was triggered by the accident, you may attribute the numbness and pain to the accident and claim medical cost for that. [1]
