I’m confused. You mention panic attacks and phobias in the question, but sharp pain and nausea in the description. I realize you don’t want to go into the details of your situation, but I do think it would be helpful if you could clarify your question a bit more. I would add that psychosomatic pain is “real pain” for the person experiencing it. Just because the cause isn’t physiological, doesn’t mean they’re just making things up. For example, people with amputated limbs will report phantom limb pain—at least that’s my understanding. Regardless, I wish you well and hope you can find a solution to your ongoing medical conditions.
