I couldn't get to sleep last night because when I was lying down I felt as if my throat was closing. I have also noticed difficulty in swallowing the calcium torpedoes I have been prescribed. Am I just getting into a tiz again or is this a side effect of Pred. ?Or a PMR symptom? I am also on Atenolol for raised blood pressure and Thyroxine for Graves Disease. Has anyone experienced this symptom? I seem a bit prone to choking too. I haven't felt so panicky before though.
