Sir I am having acute headache which is controlled by taking pantop 40 twice a day for 2 to 3 days , I feel is due to gas , because in last 3 days I had taken chole Bhutanese, rajma, biryani, and chicken . This was actually too much which I am regularly used to. I generally take 1 chapatti thrice a day only with vegetable ans dals. This problem occur whenever I eat in excess. Pl suggest a long tern treatment.
