I am sorry that you had this injury
Yes, my suggestion for you would be to visit the ER. More importantly, you should get an ultrasound
scan of the abdomen to rule of possible damage to the internal organs. The area that you specify signifies the renal angle or the area where the kidney lie. So, please check if your kidneys are fine on the ultrasound. In addition, we can get images of spleen
, liver and intestines as a whole.
of abdomen like in your case needs careful evaluation and management.
I wish you speedy recovery.
Hope this helps.
