After last night's scare (chest pain precipitated by rushing for a bus, lasting over 20 minutes radiating into my neck - took 3 doses of GTN to clear) I've had no pain today. I think the diltiazem is helping. My GP said yesterday morning I could exercise with caution, but doesn't know about last night.

Do I dare do a very light gym workout tomorrow? If not, when do you think? Any ideas?
