Severe cough. Kindly cure me fully.

Hello sir. Nov2020-first time happened severe cough,weakness,pulse rate-90,faster heartbeat,brainache,treated and prescribed azithro,Monteluk.I was better within5-7 days. Oct2022-same thing happened.this time even a serious condition,due to cough pain in chest.diagnosed and treated but not feel well even in 1 month.nov20 onwards I was in a good condition. But recently a week ago same situation happened.did all tests.cbc all in natural range. CRP,CSR was high,Ig test detected allergy.I am amazed why no doctor asked me to do all these tests.Never ever.However,I am doing these tests as I am keen on doing a full body test and the diagnostic centre owner told me to do these tests. Today blood came through cough.Now,I am afraid in this situation.3-4 doctors I have consulted in last two years but nothing fruitful happen. Kindly please please suggest me what to do.I am waiting for a right doctor as I am worrying about the situation.Kindly cure me fully.
