1) Based from the information you are having abdominal pain
in lower rt side and having bloating
, pressure and swelling. I would need you to check for pregnancy test you may first try urine test. If urine test comes positive the have an ultrasound to check if the pregnancy is not inside the tube and only in the uterus
Their are chances of ectopic pregnancy
or pelvic inflammatory diseases that needs to be ruled out.
2) Now from the mass ,based from the information provided you may have Benign tumors that arise from the adrenal gland can be either non-functioning or hyperfunctioning (whereby normal hormones of the adrenal gland are produced in excess). In some cases, these masses produce no complications, while other masses may cause life-threatening symptoms due to the excess production of certain hormones.
If possible to get it resected if your doctor thinks you do not have any risk from operative surgery just to be on safe side.
Hope it helps.
