You are not crazy, but I understand your feelings, because I've dealt with ignorance in the medical field if our issues don't fit the classic profile of a disease. I want to say I am grateful for our doctors; however, I've come to learn that they are not gods. They don't know everything. When we are miserable, we are forced to explore other options and blog with others who have the same of similar issues. I've learned helpful information not given to me by doctors. I've learned I am not crazy and there are others who experience similar issues. I have had several experiences from doctors and nurses who knew less about treatments for my issues than I did. After all they deal with hundreds of health issues, when we research a problem, we are focused on one. When I was suffering, I spent most my day on the internet searching for answers and what I learned gave me my life back.
I'll share one of my many experiences relating to this. I was seeing a gynecologist for itching in the female areas and was prescribed cortisone. Cortisone is a common treatment for a skin condition. My symptoms didn't improve, in fact became dramatically worse and I went back to the office for an exam. I was told to tough it out and keep using cortisone so it would get better. I did and was thoroughly miserable. Shortly after that I saw an allergist and had extensive allergy testing with the 5 Day Extended Patch Test and learned that among a dozen allergies, I am allergic to one class of steroids, the class that cortisone is in. After testing I called the nurse and I told her I was allergic and she firmly told me, "No one is allergic to cortisone". A simple Google search would have educated her. True this seasoned nurse may have never come across an allergic person like me, but to argue with me was truly ignorant. I sent her a letter with a copy of my test results and never heard back, subsequently I never went back to that office.
My advice is for you to learn all you can about metal allergies, metal poisoning and testing for these conditions. That said, you have few options to stop the cause because of your implant. However, ask your orthopedist for metal testing, or find another orthopedist who can refer to a facility for chelation or get a consultation with an allergist who can provide metal testing. In the meantime, start drinking a tonic of cilantro, blended in your blender. Other than the nasty taste, it won't hurt you and it does have vitamins in it.
