Need help finding good doctors in N R colony area or surrounding areas.

Hi, me and my parents are suffering from this severe form of coughing from the last 5 days, we know we may have got it from my little nephew when he visited us last week, thankfully the little kid got healed and went home.. we discovered it was some Viral infection through the pediatrician. Now cut to us, me, my mom n my dad are going through the hell for the last few days not even having a shread of sleep because of the constant coughing. the moment we try to rest our heads. we went to our local clinic and they gave us antibiotics and it didn't do anything at all, the firework like coughing stayed on. So finally I'm begging any doctors here tell me how to approach this or the people surrounding the NR colony to recommend any good doctors in the area please and thankyou .
