Thanks for the query to H.C.M. Forum.
Since 9 months passed and still you are feeling so much pain is so many places .
As far as concerned about pain in stomach and bloating
,this may be sue to hyper acidity caused by tension & stress
of trauma ( accidental ).
Swelling under rib cage
may be due to hematoma
or hair line fracture
which is very common due to accident .
Without physical examination it is very difficult to evaluate diagnosis.
In my opinion get in C T SCAN whole body to rule out any fracture and consult an orthopaedician/ physician and get their opinion.
