Thanks for the consultation. As you told that you fell down 6 days ago and your torso was twisted which is now causing pain in the left rib cage
This pain can be because of the trauma associated with the twisting of your body which may caused the muscular stretching leading to the pain. This is because our own body has so much weight that when we fall the body can have some trauma because of the body weight only even if do not have any contact with any object. Now since your age is 66 years, the chances of injury
is also more. As far as bloating
is concern, it may be associated with the rib discomfort.
I would suggest you if it is not reliving than consult some doctor and if require can take some pain killer with muscle relaxant
Thanks and take care.
