Hello,the last three days ive had some mild sharp pains under my left rib and in my chest.The doc amd burse both said they thought it was acid,but after takimg antacids,and them making no difference they thought i had trapped a nerve.Neither of them seem concered and didnt ask to see me bit the pain is still sometimes present in my chest,and i get sharp pains in my left armpit sometimes.Does anyone know what this could be? The way the doctors responded has put me off going to hospital for the time being as im not in agony but just wondered what it might be.Thankyou
