Thanks Ashley & CT. I do have a new heart diagnosis(murmur), but I have to wait to have the gravity of it tested, and I also have parastheis by carpal tunnel syndrome, so it's scary. All this happened with some virus and/or asthma symptoms, and ended up in ER twice. It's better safe than sorry. Another test is lung, but all this is waiting. The doc said one of his and a colleague's patients collapsed from asthma....I think I'll just take it easy, and freeze my gym membership, which has been sporadic for 5 weeks.
