Hello i have gone through your query.first of all its gud that you have stopped takin gutka or pan masala.bt as you have taken it before you got a condition called oral submucous fibrosis(osmf).are you having any burning sensation also while taking spicy and hot food. Treatment for osmf is to quit the habit first dat you have done.take antioxidant tab with lycopene like ms fibro tab twice daily for three months.depending upon the severity kenacort gel or submucosal inj can be taken.check whether your mouth opening is three finger , two finger or even less.for severe cases surgical procedure can be done.certain mouth exercise also helps improving the symptoms Visit a dentist to find out severity of your condition. Hope this ans helps Regards Dr. Shesh
