Squeezing pain under my left breast Q: Hi Dr., I m a 49 y/o male, 5 10 tall, 83kg in weight, don t drink and smoke. On Propranolol 20mg x 3 time/day for palpitation and blood pressure. My palpitation and blood pressure started July last year, in the wee hrs in the morning while sleeping. Rushed to hospital and said the cause is anxiety. Until to-date, the doctor/s could not figure it out the actual cause of my palpitation and blood pressure. Stress test (treadmill), Echo, and ECG were done and shows normal. Have done laser surgery for nasal swelling a yr ago. Have been treated for mild bronchitis, and use inhaler whenever I feel chest tightness. Palpitation & BP are under control. My total cholesterol test today shows 4.39 mmol/L.Past few weeks, I am getting squeezing pain under my left breast (off and on) which is quite painful and lasts for 2 to 3 mins. I m concerned about the pain and seeking help. Please help me. Thank you.
