CT. I would agree with the Lyme analogy. I took a family member to a lyme specialist yesterday ( she has most of the lingering of long haulers symptoms. This most recent Dr. has identified the issue as a Mast Cell problem- My sister is supposed to try every first and second generation anti-histamine note the response and decide if any one of the multitude works! My personal opinion is that that is insane. Long haulers are VERY lucky that the med community it trying to get this figured out- Post Acute Lyme patients not so lucky.
