Hi and welcome to HCM. Thank you for your query.
This can be valley fever
and you need to be tested. But also it can be any other respiratory infection and this is more probable. Valley fever microbe may be in our body in inactive state if this was disseminated and it can be activated at any time if this wasnt completely cured.In most cases it doesnt recur, but you should rule this out by more detailed blood tests
Wish you good health.
