hello there ,
Appearance of red bumps on the oral mucosa
of soft palate, tenderness and sensitivity to hot and cold indicates inflammation .
It may be caused due to several reasons like deficiency or certain vitamins especially vitamin B12 and vitamin C.
Maintain good oral hygiene
by practicing regular mouth rinsing with lukewarm saline water or antiseptic mouthwash like betadine or chlorhexidine
start with multivitamin
supplements for 7 to 10 days and vitamin C lozenges will help in resolving the problem.
avoid alcohol , carbonated drinks , tobacco chewing
and smoking as these may worsen the area affected.
Apply oral antiseptic ,analgesic ointments like dentogel or mucogel topically over the affected area
i hope this helps ,
