My mother has had a pain in the middle of her left side this past Monday, under the rib cage, that was terrible enough to go to ER but no kidney stones as were suspected, no issues with blood work and nothing on CAT scan. Since that day pain is still there but has subsided, but a low grade fever ranging from 98.7 to 99.7 has persisted each day up until now. Appetite has improved since Monday, no nausea. Energy level low, but better than it has been.
