I cracked my neck and my shoulder hurts now. help what can i do for this?

ice: Ice for about 45 minutes, 3-4 times a day, for inflammation and swelling, never apply ice to the skin, always over a towel or clothing. If the muscles are very tight or have spasms, follow this by heat for about 20-25 minutes to help soothe and relax tight muscles. Gentle exercise also helps. Walking, gentle range of motion and stretching exercises. See dr. If persists or worsens.
