If the sprain is to a finger or other part of the hand, immediately remove all rings, bracelets and watches. Stay off the injured limb. Continue to apply ice for the next 24-48 hours. If the problem persists or worsens, get it checked out. There may be a fracture or tear that needs specific care.
Nausea is different from vomiting.
Vomiting is the body's way of ridding itself of things it doesn't want. Infections can cause nausea and vomiting, as can overeating, food poisoning, pregnancy, medication, too much alcohol, or emotional causes. Eat bland foods in small amounts throughout the day. Some examples of bland foods are applesauce, jello, crackers, bananas, rice, toast, and broth. Some people find that water makes them vomit more.
