I was assaulted with a machete. i had a deep cut at the back of my head. although the doctors stitched the wound and said its ok. its 6 weeks now but i am having a blurry sight. when i read i words, i see double. although the wound is closed from outside but it is still healing from inside. i only lay on my back due to other injuries on my shoulder thereby placing the head wound on pillow. i dont know if my sight will return to normal. i couldnt see for some minutes after the cut on the head
