I do not recommend the doctor
I am somehow not got convinced with the explanation given by Dr.Apeksha. I am allergic to dust, pollen, pollution, etc. My respiratory track is getting affected due to these allergic problems. My nose gets blocked and makes me feel uncomfortable to sleep during nights. I literally breath through my mouth which gets dry completely and wakes me up in the middle of night. I somewhere read salt therapy would be the cure for this problem, but somehow did not get that convincing message when I met Dr.Apeksha. I also felt Rs.500 paid as consultation fee was not worth. Altogether I still have some positive hope on "Salt Therapy", but will get back with some more search.
