My son is suffering from high fever (100-102) cold and cough from 7 days. Initially doctor told viral fever and prescribed calpol 250mg, relent D+, meftol60( in case fever > 102). After 3 days fever down to 99. Again next day fever gone into 100-102 with stuffy nose, sevier body pain, cough, sore throat, feeling chill and sheverish. Again I took my child to the same doctor and blood checkup done for CBC, typhoid, Malaria, urine test and all are normal. Doctor said he's suffering from viral flue and ask me to continue the same medicine calpol 250mg, relent D+, kidicare-D. Now it's 7 day's and his fever not down and lost his weight from 16.8 to 15.8kg. I'm feeding his fresh fruit juices, glucose water, and fluids but he's not. insisting to take anything..I'm really worried because his condition become worse. Please guide shall I continue thesame medicine or consult second doctor opinion. I'm consulting this pediatrician from my baby was 6 month old and was happy with his meditation,..
