question: I have had a cold for approximately a week. I woke with a lump in my throat this morning and coughed / gagged very hard this morning. My chest felt like I'd been hit by a bat and my chest and arms started to tingle. My arms had a numb feeling. I felt dizzy so I laid down. I fell asleep and just woke 10 minutes ago. My left arm is still sore and the lump is still in my throat.
