Suggest Remedy For Swelling In Toes

I had a atery puncture on my left hand at casulty, and since then, my hand goes purple/blue and then back to its normal colour. Also, on the left side, my toe is always swollen and it feels as if someting sharp is slicing. Now, my right hand is double sized and swollon. Another thing, I have this pinching sensation in my head. Doctors at casualty said that as long as the hand is pink and warm, it s fine. I also feel pressure on my right arm and my left leg - as if it s going to expolde. However, I was wondering if this is normal - do you think the swolleness would come to my brain eventually?
