hi,
you seem to have acute bacterial infection of the lungs, you should have gone to doctor earlier it would not have increased so much,but since you have started on antibiotics now it will surly reduce,
asthma symptoms always increase during infection of respiratory system ,it does not mean that your asthma has worsened, but if without any infection if you have to use your inhalers more number of times then your asthma is increasing.
now coming to your question losing voice ,it is common for such a thing to happen when you get severe infection of throat you have to go to doc and he will start antibiotic, also with one episode of headache we cannot diagnose
migraine ,you have to visit
neurologist if there is doubt he will diagnose it correctly and guide you further ,asthma and migraine are not connected.
now coming to your asthma symptoms i suggest you do the following
for one or two attacks a week ,use broncho dilator it should be enough
for more than 2-3 attacks i suggest you use
steroid plus long acting broncho dilator,
it is most effective treatment present currently, the dosage will be decided by you physician after examine you and on taking detail history of attacks.
i also suggest you get yourself tested for
allergy, it is called skin prick test you will know what you are allergic to, then if possible you can avoid the allergen or you can start treatment called immunotherpy. this is currently the best treatment available and your symptoms will easily reduce by 80-90 percent kindly visit immunologist he will do skin prick test and immunotherapy
