Hey doctor,6 days ago i randomly started feeling awful, but not flu or vold symptoms. Over the 6 day period, i have had severe cold sweats, lower back pain, a temperature flux of 96-104 and now abdominal pain. I feel like i was punched in the stomach. Bloated, but the inside feels empty. It is mostly in the center chest, below the ribcage. What can i do to help the pain???
