Welcome to the community.
For many with these infections, flying in an airplane will create our symptoms to increase.
Also, there are relapsing/remitting strains of Lyme disease, I know I've dealt with them, and it sounds like maybe that's what you are dealing with. Lyme disease is a bacterial infection that is actually quite difficult to treat generally.
