Hello, You have symptoms of thin edges at sublingual papilla which is mainly due to dehydrated ora cavity, acid reflux due to systemic disease and could be due to an allergic reaction. Need not to worry. I would suggest you drink plenty of water and chew on sugar-free gums to stimulate salivary flow. Avoid intake of sharp and spicy food. You should gargle with a numbing solution containing Lignocaine for relief on tongue and pain. You can take an anti-inflammatory painkiller like Ibuprofen. It will start improving within a week but in case if the condition does not resolve to consult oral physician once and get evaluated and start treatment accordingly. Go for blood tests as per prescription. Hope I have answered your query. Let me know if I can assist you further. Regard, Dr. Harry Maheshwari
