Birds/poultry can get TB.
Make sure your Dr knows what species you keep and their health history.
If you have multiple ill birds, so ill you have to cull, it would be a great idea to have one or more sent to the state lab for testing. Most states do this for no cost or low cost if you can get them the bird. They have great interest in detecting diseases that impact human health as well as industry heath. You can sometimes get good answers to what ails your flock, sometimes not- but can often be of great benefit, and usually less money for the info than lots of OTC meds from the feed store. Worst case scenario, something might get detected that gets the state more interested in your place that you really wanted- but my take on that is- if there is something creepy at my house that can get me sick, or severely impact my county's farm industry- I want to know. Worms, cocci lesions, mareks, CRD/mycoplasma, histoplasma ect- they don't care- not specifically zoonotic. TB would be of interest to them. Avian flu- overseas version- would be in interest. Exotic newcastles would be of interest. Chlamydia as well.
Histoplasma is in the soil, it is more of an environmental contaminant, people can get it as well as chickens (and other mammals). Not really zoonotic, as we get it from the same source. We can get exposed in areas this fungus is around, because it likes to grow & sporulate in chicken poop. I think it is mostly a mid-west issue for people and animals.
Some will even pick up via local poultry extension agent. Call your state vet's office if you want more info. Call local vets and find one who sees exotics/birds- they can also assist you in cull & packing and sending if you do not want to do it yourself.
Hope your Dr can sort this out, and you feel better soon.
