I have cystitus, allergies inflamation bladder, hernia esaphagus, asthma, stomach inflammation nerve damage, easily get sick could it all connect?

In some way, yes. They are all connected in that they are all with you. Also, they share an inflammatory quality and probably have something to do w/ your auto-immune response. This may be helpful since getting a handle on one might improve others, but they are all challenging to health care providers. Work w/ your Drs like a team. Ask about accupuncture possibilities too. Best!
