Injured arm 2

Is my arm healed?
Or I just got used to it?

But one thing that i notice, the pain comes back bit by bit when I practice my Kata.
When i spar, it remains quite alright...
Except the upper arm of my left hand starts to feel some funny feeling.
Not the feeling of tired,
but pain.

The idea of training a new kata, wanting to compete with only shitoryu kata, seems to be more and more difficult.
Either i trained with an injured arm, risking injuring it further;
or rest and might not be good enough for the competition.
