Detailed Answer:
Hi XXX,
Thanks for the query. I understand your concern.
Mouth ulcers like Canker sores( painful, round sores ) - Psychological stress is basic cause of canker.. being triggered by following factors. -but looking at your previous queries I feel the commonest possibilities in your case seem to be-
- B complex deficiency caused by bad stomach/ worm infestations you had recently
had damaged the normal intestinal flora( Lacto bacilli-which sre responsible for B complex synthesis in our gut ) & this has caused mouth ulcer.. gone painful because of secondary infection. Spotting & eliminating the causative organism by specific treatment would be the answer to this cause.
- A broken tooth or misfitting denture can cause friction ulcer again secondarily infected to be painful,- Correction of the cause by dentist would help.
- Negligence to oral hygiene can cause it/ oral thrush
- Oral sex with a person having genital infection
* You had already tried mouth gels...& are also planning for a travel.. so it's a time to get it investigated & treated specifically,
- Get consultation of your family physician for your digestive problems. A stool examination will throw light on the causative organism/ worms,
Your family physician would offer a specific medication course would help you thereafter. This would be supplemented by B complex replacement ( may be injectable.. as you are in hurry ) to be followed by probiotic( Lactobacillus supplement ).
Investigations for STD( if needful ) followed by specific medication would also be possible with his advise.He may refer to a dentist for expert advise if needful.
- A dental check up to exclude / confirm gingivitis/ broken tooth, oral thrush would facilitate specific management. Consult a dentist for expert management
* Home care-This is to ease the problem & prevent it in future.
Eat bland food, do warm water gargles,apply Boroglycerine or XXXXXXX ointment, drink plenty of fresh water, have fermented food articles(Idli, dosa, Dhokala. curds. butter milk, yeast preparations) & sufficient fibers in diet ( so as to have clear motion every day & MOST important is to follow doctor's advise & medicines strictly.
This way apart from stress less psychology, with expert's advise & home care you would definitely overcome the troublesome condition & enjoy your tour.
I hope the answer was both informative & useful to you. Any follow up query is welcome.
