You already know a lot about your condition and that definitely helps.
It is important that the sensitivities to aspergillus
and moulds are defined properly.
Was IgE positive to aspergillus or mould mix, either by skin prick test (red weal and flare) or blood test?
Or was it specific IgG to aspergillus that was positive? Was a precipitin test done?
The precipitin test is to exclude a form of pneumonitis
pneumonitis and occasionally can look like fluid in the lungs everytime an XRay of the chest is done. This hypersensitivity is driven by IgG antibodies
and therefore a chest physician must be involved in your case to ensure this is not what it is.
Occasionally, a course of diuretics is given to see if the fluid disappears and can point to a cardiac problem. A 2D ECHO will be helpful to know the ejection fraction
and ensure there is no LV or RV failure.
I hope that was useful
