I am feeling burning sensation in my feet for some days, i have acidity that has increased in last few days?

It could be a reaction to a medication, but you could have diabetes and not know it...and it could be the beginnings of nerve damage from untreated diabetes. You need to have a fasting blood sugar test done, to determine what your sugar levels are... If you are already a diabetic and you know it, you need to make sure your levels are being managed... There is another condition, called restless legs syndrome, that sometimes is felt in the feet, rather than the legs, and it can feel like burning, rather than the "ants crawling on your feet/legs" feeling that some people get... If this isn't a reaction to a new medication and it doesn't go away, you do need to see a doctor. Sometimes it can be a reaction to low iron, but if not treated, can lead to permanent nerve damage. The condition is called pernicious anemia, and I know first-hand, because I suffer from it, and have to have iron transfusions from time-to-time.
