Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain the symptoms seems to be consistent with viral infection leading to the symptoms of stomachache, congestion,
sore throat and bodyaches..
I would suggest you to consult an Otolaryngologist and get evaluated and he can advise you to go for a throat swab culture to rule out for the exact cause of pain and redness in throat..
He can advise you to take antibiotics like
Azithromycin or
Levofloxacin, take anti-inflammatory painkiller like
Ibuprofen, do warm saline gargles, steam inhalations and use a humidifier in your room..
You can chew
Vitamin C pellets and suck throat lozenges..
Drink plenty of warm water throughout the day..
Avoid spicy, chilled food and take ample of rest..
Hope this information helps..
Thanks and regards.
