I have been on 10mg amlodopine for about a month now. Last week i noticed/ felt a tightness of my ankles .. like i had bad sunburn and my ankle was fairly swollen. I rested with my legs up which helped but after walking about again same thing happened . This carried on for at least a week and suddenly was gone! Is this normal? Also i have been feeling like a "pricking" sensation in my chest, on the left. Should i be worried ?
