Hi..
Thanks for the query..
As per your complain Oral
Lichen Planus is an auto-immune inflammatory disease leading to formation of red and white painful lesions on mouth as well as can cause lesions in other parts of body also..
The cause is mostly unknown although a few causes like
Hepatitis vaccine, painkillers belongings to NSAID's, Tobacco dipping, very poor
Oral hygiene, allergy reaction to certain foods, dental materials etc can be predisposing factors..
Lichen Planus is almost a life saver disease and the lesions may continue to occur all the life..
The treatment that can be prescribed is topical application of
Steroid based ointment over the painful areas..
Numbing gel can be applied to reduce pain in the painful lesions..
In very extreme cases immunosuppressant are advised to patients but only in very extreme cases due to other side effects of immunosuppressants..
Hope this helps..
Regards..
