Hello As you mentioned that you are having cough but after pickle & rice ? This type of cough may be due to some allergy caused by certain food ( as pickle & rice in your case). Now either avoid rice and pickle together or take some antihistamine drugs like monteleukast+ levoceterizine , as required and whenever you need. If cough present without pickle & rice , may be due to allergic bronchitis and known as asthmatic allergic bronchitis . When such type of patient visit in my clinic I prescribe them monteleukast+ bambuterole tablet once or twice in day till complete relief. Hope this information will help you.
