I’m at my wits end with this… I have literally been checked for cardiac issues, kidney, stomach, neurological… the vascular doctor was a joke. But I will keep moving forward because this can’t be normal to live with.

That is exactly my plight. I have told the innumerable pain docs over the years, "Look, the principle of cause and effect...I am in severe, chronic pain. That is the effect. There is a cause. Now, it's your job to find the cause.". Each doc just wants to put a band aid on the pain with injections, PT, and who knows what else. So, I say, "How about reaching out to the medical community? Surely someone has had experience with this". Oh, no, they say. I am the expert. I don't need any other doc chiming in. Bah, HUMBUG!
