Gallbladder pain is nothing to mess with, it messes you up. Once again, I come to find that it's related to my CPTSD/PTSD, which doesn't surprise me since this is where bile is found in your body and bile is associated with anger, irritability and proper digestion. At the same time I also have discovered that it doesn't always show up with blood work. There are times when it is so dormant that your body grows accustomed to it being there. None of this is good, especially when you're the one feeling its symptoms. Fortunately, there are some things you can do for it...
Accupuncture with your TENS machine can also help relieve some of the pain from gallstones by reducing spasms, easing bile flow, and restoring proper function.
Taking magnesium helps ease gallbladder spasms and pain. This makes sense because it also helps reduce anxiety. However, there have also been studies showing that deficiency will lead to the increase of gall stone formation.
Drinking lemon water (3TBSP lemon + 8oz water) in the morning is good for helping your body balance its pH level, which is important so your body runs efficiently (something you're struggling with if you have any of the conditions this site talks about). You should add 1/4 tsp cream of tartar to this to help improve bile flow. Additionally, taking 1TBSP of olive oil first thing in the morning and again at night will help get things moving along your gallbladder tract smoothly.
Peppermint tea is also an option, but if you're like me and don't drink tea, you can also try aromatherapy. A combination of lavender and peppermint work well here because they both detoxify your body. Peppermint also eases stomach pain, improves digestion, and relieves nausea while lavender is known to help you relax. (Remember, pet bird owners should be VERY careful using aromatherapy of any kind because it can kill your bird.)
Stretching is another option because it'll help you relax and open your body up to doing what it's supposed to do naturally.
While the main thing you'll want to do is get your chronic bitterness under control, hopefully these remedies will also help along the way. Please remember, since I'm not a doctor, these are merely *suggestions.*
