Experiencing Constant Numbness To Left Of Stomach, Pressure. What This Could Be?

yes, im experience constant numbness to the left of my stomach and pressure. it doesnt feel internal but its been ongoing for a week now and doesnt seem to be getting better. any idea what this could be ? it goes from my rib cage , down to my hip . and its on my side to my back but not my back . im also experiencing numbness in my left last two fingers(pinky and ring finger) and stiffness in my shoulder. all started at the same time.
