I am assuming you are speaking the truth.
I have to ask if your doctors have tested your hormone balances, tested for chemical poisoning, and tested for neurological disorders as well as simple diabetes , an A1C test.
at least.
This could be autoimmune , also.
Seems like you may have a food allergy or chemical poisoning you are unaware of? idk
Don't just assume they have tested for all that , get copies of the results and look at them yourself.
Ask for the tests you need.
The real life doctor from the tv show 'House' is Dr. Lisa Sanders and she also authored the book 'Every patient tells a story'.
She is on the faculty at Yale University and may have some good ideas if you contact her there. She does have email .
You need a comprehensive evaluation and testing done. If you have any idea of any poison you may be injesting, or food allergy, tell them.
It sounds like it could be neurological also.
Just find the cause ,
I know of a vitamin/mineral supplement that you can take that absorbs in the upper stomach and doesn't require the digestive process to absorb, you can also apply it to your outer skin to replace the nutrients you need , it is made by doctors microbiologists and they have made it ionic/nano size for absorbtion reasons.
Their products are sold at rainbowminerals.net and you should /can call and talk to Tina.
the very best wishes
