Hello. I am having horrible pain, swelling , redness, and heat in and around my navel. The pain is worse toward the inside of the navel with the swelling, redness, and heat mostly about an inch or two around the outside of the navel. Any ideas of what could cause this. It is painful for me to sit down and stand up. Once I am down or up, the pain isn t as severe. If I lay on either side or my stomach the pain persists.
