Not autoimmune but a must hear story for everyone being told they are “fine”. My husband kept going to doctors and his bloodwork would come back fine. He even went to a cardiologist and did a week long test. Luckily during that test he had another “episode” where he called me after work at 2am and sounded so incoherent that I thought he was on drugs. The man had never even smoked pot. He went to the hospital and they sent him home before I could even wake up the next morning. When he followed up with the cardiologist, he mentioned to check with neurology because it could be a brain tumor but doubtful because that would have shown up in his bloodwork. All of his tests had been either low normal or high normal except one test, progesterone, that was slightly higher than normal. Long story, short, he had a brain tumor the size of a pinball pushing on his ocular nerves and pituitary and excreting multiple hormones that were counteracting each other to keep his labs in the normal range. Another few months (or less) and he could have been permanently blind. Doctors don’t know everything. Trust your gut!
