Hi..
Thanks for the query..
As per your complain canker sores along with painful
swollen gums along with burning sensation in esophagus and stomach is a clear indication that you have side effects of the antibiotic intake causing Apthous
Stomatitis and Gastritis..
You should consult your treating physician and get evaluated and a thorough clinical evaluation done..
For mouth ulcers and painful gums you can be advised to gargle with numbing mouthwash containing Lignocaine..
Do warm saline gargles..
Gargles with 1:1 solution of benadryl and
milk of magnesia can help..
Apply numbing gel over the sore for relief from pain especially during eating..
Take a
multivitamin tablet for a period of 15 days..
Avoid spicy, sour and acidic foods..
For burning sensation in stomach you can take
Pantoprazole empty stomach in morning till you are on medication..
You can take antacid like milk of magnesia half an hour before meals..
Take plenty of probiotics like Yogurt..
Avoid spicy and heavy meals..
Hope this information helps..
Regards.
