I am 22years age and weight 75 suffered with palpitations and chest heaviness or pain at centre of chest, shoulders and biceps centre of back that usually lasts for few seconds and is like on/off comes and goes. Uneasy in stomach, Also pain in chest while walking for less distance. I met doctor and he said it was only due to gastric and muscle aches but I took ecg and complete bloodcount test which found to be normal. Now I am feeling normal and all those gone since 15 days. Are there still any tests should I go while my doctor advised me to start meditation to suppress anxiety but not required any tests. Please specify.
