Actually, it is..
Could be colon or spleen, or it could be directly caused by stomach too. (they are related to liver/gb problems, anyway) but after GB attack, bile ducts are most obvious issue. Something is stuck in the biliary duct, in the V bone area, probably where gallbladder connects to liver bile duct, most likely backing up bile in the liver area on left side of the body, and puts the pressure on some nerves in that area, it also pressures two major blood vessels going down from hearth, that will create hearth palpitations . It will most likely make your left arm/leg to go numb..
Just take an easy,..
Try long term beetroot/leaf supplementations, lysimachiae, chinese Gentian,
Liver Flushes are a must,... put castor oil pack on the V bone area or just plain hot/warm bottle for hour or two, every day... relax your body,.. stop eating meat for now. Eat soft cooked vegies,.. No sugar(especially no chocolate), period
Also try Turmeric extracts, Amla, Vitamin C (sodium ascorbate).. AF betafood/Beta TCP,. Juice apples/beetroot (small portions) eat black sessame seeds.... Study, learn, try.. and everything must be long term.
