Hi, You were having congestion symptoms at Sunday and Monday It could be viral upper respiratory tract infection. Now if after two days if you don t have symptom as mentioned than no further work up needed But if congestion still present or if fever present than your work up needed as follow. - CBC - Auscultation - ASO titre - Chest x ray if needed Peripheral smear examination for malaria parasite if sweating present and if malaria suspected For congestion relief Benadryl like decongestant drug prescribed Salt water gargle done three times a day Hot water used for drinking Vitamin C lozenges taken three to four times a day If fever increasing and if it seems bacterial infection than antibiotic started and sputum examination can be advised. Consult physician for examination. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Parth Goswami
