Hello and welcome to Healthcare Magic. Thanks for your query. It is possible that these episodes could be indicative of a panic disorder. The usual symptoms of panic attacks are out-of the blue episodes of anxiety, racing of the heart, increased sweating, shaking of the hands, dizziness, tightness of the chest, difficulty in breathing, feeling like you are going to pass out or die, etc. Valium (Diazepam) is a sedative and anti-anxiety medication. If these episodes are persistent or causing you disturbances in social, occupational or day-to day functioning, then I would suggest that you consult a psychiatrist for further evaluation and specialist management. The excessive burping and associated symptoms could be indicative of a gastric acidity problem. You can avoid this by having your meals on time and avoiding spicy or oily foods, carbonated or caffeinated drinks, etc. You can take an over the counter antacid for quick relief. If the symptoms don t subside with these simple measures, then you may need to see a doctor for further treatment. Wish you all the best.
