Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain sore throat can occur due to causes like throat infection that can be due to bacteria or virus.. It can also be due to causes like Acid reflux, post nasal drip,upper respiratory tract infection etc.. Bruised appearance of soft palate seems to be due to inflammation and as the sore throat will subside the bruising of soft palate will resolve.. You should consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and throat swab culture and pH level of throat can help in diagnosis and treatment can be planned accordingly.. In case if there is throat infection you can be advised to take antibiotics like Azithromycin, anti-inflammatory painkiller like Ibuprofen, doing warm saline gargles, steam inhalations and suck throat lozenges.. Chew Vitamin C pellets.. Avoid spicy and chilled foods.. Drink plenty of water.. In case of acid reflux proton pump inhibitors like Omeprazole or Pantoprazole and antacids along with dietary modifications can be advised.. Hope this information helps.. Thanks and regards.
