Dont know simple acid reflux or GERD.

Before 22 days I have a chicken pox now its cure but Past few days I have dry cough burping and gases and very rarely sometimes heartburn and throat irritation. Past history was Same thing happened with me in September 2017 that time ENT specialist check me and dr prescribed me sompraz and gaviscon for 15 days and symptoms disappeared and after that did not came.Now same symptoms and feel like something stuck in throat.Due to lockdown I have take online suggestions with dr.Dr prescribed me Sompraz L so i have taken it in morning only 5 days and then stopped. While taking this all symptoms disappeared and feeling well. But yesterday night I have ate spicy masala rice and after that heartburn start in night and its gone after 1 2 hrs after drinking water. But I feel like some mild symptoms are come back which feel like constant need of throat clearing and small amount of dry cough. So my question is should i take sompraz L again and how many days to continue it and what frequency.Thanks
