Daviezmom, have you ever read about adhesions? Well, 93% of people who have any abdominal surgery get adhesions which can cause a dull ache, a pulling sensation, etc. Scar tissue begins to form 3 to 5 hours after surgery ends!!!
What I just read is that the organs in our body are slippery but if a piece of gauze, a surgical instrument, a gloved finger touches one spot, that spot gets 'sticky' and a thin fibrous membrane can grow and attach that spot to another organ, muscle, etc. The doctor told me that 'some people have pain when taking a deep breath that feels like their lung is pushing on their liver'. Freaked me out! That's when I read about adhesions. I had 3 abdominal surgeries in 3 years plus a port in, a port out in my upper chest for chemo, etc. I'd never mentioned the discomfort because I just always figured scar tissue from the last surgery.
Sounds like you might have some adhesions from the gall bladder surgery and maybe a piece of your intestines is 'stuck' to your liver or something. The drawings I saw looked like a stretched rubber band and it also said the organs don't GROW together and affect each other, just get attached by this thick membrane.
The liver (I had 80% of mine removed) has no nerve endings. When people have 'liver pain', it's because the liver has either swelled huge or has loads of fluid around it filling the 'sac' that protects it and pushes against other organs. You could NOT have good liver readings and have that going on.
I'd bet it's scar tissue from the surgery!
