Hello and welcome to JustAnswer,
wouldn't expect to learn anything about this from blood work or stool or urine.
would expect that a chest xray would be a good place to start followed by a CT Scan of the lower chest/ abdomen and pelvis....
are those coming up for you?
and how about an endoscopy where a Gastroenterologist looks down into the stomach with a video camera?
could be an abdominal wall hernia especially if you have had prior abdominal surgery
these can come and go and do tend to be positional
i did not see you in the chat.
my suggestions for you are as follows and based on the fact that you can actually feel something there under the rib. if you can feel something, something is there, and imaging studies are what is needed and they would include, depending on the exam your physician does....
1. an ultrasound of the area to see if a hernia can be identified or a soft tissue mass
2. a CT scan with contrast through the area
one or both of these would identify this lump or nodule, and depending on where it was located and other characteristics of the findings a surgeon might need to do a biopsy either with a fine needle or with a surgical procedure under anesthesia.
the left upper quadrant of the abdomen contains the stomach and spleen and this is also the lower portion of the rib cage so there's not too much here that is worrisome from my perspective, but a nodule or lump anywhere that is new and causing symptoms needs to be investigated and diagnosed. they are, occasionally, dangerous, and, occasionally, indicative of other problems which are not obvious from the symptoms.
I am standing by if you have any questions.
Hello. I would like to help you find an answer.
Are you taking any medications?
My recommendation would be to get an ultrasound of that area to look for anything suspicious.
I highly doubt cancer though.
Okay. You need to have a HIDA scan.
It checks functionality of gall bladder. Gall bladder can not be pumping properly even if ultrasound is normal.
It's called biliary dyskinesia.
Thanks. Please accept.
Pain after eating is a cardinal sign of gall bladder issues.
Could also be the stomach. You need a HIDA scan and an endoscopy.
