I have mild pain in lower right abdomen, lower right back soreness( not felt during lying down), and mild chest pain where heart is located when under stress. The swelling in the lower right abdomen increases when I hold my urine for extended times at work.  I also lift constantly and stay on my feet all day at work.
Hi. Thebest way is to get the preliminary ultrasonography done to see the status of the kidneys and whole urinary system and other organs. This would help to get a proper diagnosis which is so much important to get the right treatment.  Clinical examination would see for the swelling, whether is due to kidney/ hernia or so. It points to the area to be investigated thoroughly.  The chest pain due to stress can be due to costo-chon Chat Doctor.  Please share this with your treating Doctor.
