Oh BL...I can't imagine how you must be feeling. I'd be a wreck too! I can't understand why doctors are that way. Knowing what's wrong but giving you no inclination of what it is. Maybe he just wants to be sure what really is wrong instead of worrying you. (too late for that though huh!)
I'll keep you in my thoughts and prayers that all results come back fine! Take care and try not to worry!!!
