Hi thanks for contacting HCM.... If you have gastritis or acid reflux than it can irritate the throat and sore throat can be there .... For that take omeprazole capsule on empty stomach before meal for two weeks .... Avoid excess spicy foods. .... Avoid smoking and excess fried foods ... Drink more water ..... Salt water gargles done .... Hot water drink daily ..... If needed dilute betardine gargles can be done as an antiseptic to sooth throat .... If inflammatory swelling at throat more than short term steroid can be given .... If your sore throat worsen investigate with aso titre (for strepto ) and swab taken for culture .... Hope your concern solved ..... Take care ....
