Hello Dr. I met with an accident and had a hit on my back near kidney at left side, after 1 years now I feel the pain. I am having sleepless nite due to severe pain in leg at joints and back, feeling so ill and getting tired easily, sometimes I am having numbness only in left leg. I have a vomiting sensation sometimes too. So please help me what does that pain mean? Whom do I need to consult? What kind of medication do I need to follow? Thank you.
