I have consulted online using Practo for my fever.One doctor suggested me to take dolo650 and zincovit tablet for 5 days. My fever was very low and coming and going. After 5 days of continuing my tablet did not improved my fever and Again I met to other doctor and he did few checkup and my fever was 97.7 and he wrote dolo650 and Moxikind-CV 625 to take for 5 days. My fever was ok for two days and now I feel fever at night and body pain still persists. I have slight fever. Should I take blood test to know actual cause . What are the test required. Or what should I do. I still feel weakness and sometimes light fever and body pain.
