AL Amyloidosis maybe?

Hello. I need help/advice...36 M
For the last 6 months I am having these health issues. To be more specific, I think it all started somewhere in April last year, i was having these problems of dizziness sometimes, upon standing or idk exactly...and my left leg hurt sometimes like from the back of the knee and goes to foot, it still occurs sometimes just like the dizziness as well. Then in October sudden iron deficiency anemia, high cholesterol and tryglicerides and i never had problems with these until now, sudden weight loss, and i cant get any kilos back... Dry flaky skin on my knees and over the heel, soft and vertically ridged nails, arthralgia/crepitus sounds in my knees, occasional bone pain but always same spot (upper arm), and most lately tingling in my fingers of left hand. And I think my tongue is a bit enlarged ,it looks scalloped like. I visited gastroenterologist, endocrinologist, immunologist, and a few more internists. We did like all sort of tests: CBC normal except hemoglobin and hematocrit low, 3x abdomen ultrasound clear, TSH t3 t4 OK, all hormones ok...colonoscopy ok, gastroscopy ok, MSCT of abdomen and torax OK, all ANA/ENA and RF ok. The only thing left is MR of small intestine. Echocardiogram is ok too. They are saying that I am fine and that i need a pscychiatrist. And now this immunologist is saying i am making symptoms up, didnt even wanted to look at my tongue and shes saying i have IBD and she is treating me with mesalazine without any proof I have IBD or Crohns on small bowel. Here is latest SPEP... Idk what to do next...im desperate. Pls help
