Hello,
You are suffering from a feel of pressure in your left arm and shoulder since 36 hours. You have felt similar discomfort earlier but it has disappeared so you didn't pay much heed to it. You have not given any medical history of your past illness or disease / surgery. Left arm pain is commonly due to problem in the bones, muscles, ligaments or tendons in the shoulder. Sometimes, the discomfort in the shoulder joint may indicate pain from the neck or a pinched nerve.
Medical conditions that may cause such symptoms are developing CAD, coronary artery disease, heart ailment like angina,
heart attack, MI, stroke (CVA), etc. You are suggested to get clinically examined by a GP / cardiologist. Get all routine cardiac tests, lipid function tests,
stress test, CBC,
Urinalysis, Echo, EKG done to detect pathology causing you symptoms. You will be treated accordingly.
Other medical conditions that can cause similar symptoms are
frozen shoulder, shoulder
tendonitis,
shoulder arthritis, neurological problems, etc. Get clinically assessed so that treatment can be started at the earliest. In the meantime, do moderate exercises and regular walking. If
overweight, loose weight. Keep your blood pressure and blood glucose level at control.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
