Hi.. Thanks for the query.. It can either be an allergic reaction while there is also a possibility that you have got chemical or thermal injury of the roof of mouth leading to tingling, inflammation and bumps.. I would suggest you to start gargling with a solution containing 1:1 concentration of milk of magnesia and benadryl.. Do soda bicarbonate solution gargles. Do warm saline gargles.. Avoid all those foods or drinks after taking which you suffer these symptoms.. Before you take your meals gargle with numbing mouthwash containing Lignocaine as it will not cause any pain during meals.. Suck ice to reduce inflammation and healing of bumps.. Drink plenty of cool water and avoid spicy foods.. Hope this helps.. Regards.
