I had achey feeling in chect and throat when walking outside in cold weather so I told doctor. Went to hospital for ECG. said she thinks minor angina. Doctor gave me atenolol 25 twice a day, also simvastatin, aspirin 75 and a glyceryl trinitrate spray. I have not had the blood test from doc yet, but i got a cholesterol test at chemist and it was low 2.4. had good cholesterol. to go back to hospital in a month to get checked. Had uncomfortable feeling in chest area and felt as if a wanted to breath in slowly and breathe out quickly. I feel quite worried about it.
