Thank you all so much for the replys. Like I've said before I am so overwhelmed by your help and concern. It's a relief to know this happens often, and could turn out to be nothing. It didn't show up on the CT scan, it just lit up on the Pet.(which I know can catch smaller things).
David, I didn't mean to remind you of your appt. in Feb., but thanks for sharing.
Tim (Stoj), I live 60 miles south of Pittsburgh. Been here all my life!
Thanks for the advice about antibiotics, and I do have a chest x-ray scheduled before my appt. with the thoracic doc. Geez, thought I had enough doctors to deal with!! And Len said it all about the YO YO life. You know the worst part about that is having my family have to live it also. Me, I can handle it, I just can't handle seeing them have to go through the ups and downs. I am in awe of all you care takers and loved ones. I know I'm blessed with the family and friends that I have. Have a great day!
