Hi Chipper! Actually, if the upper limit 50 is normal, 150 is 3x the upper limit of normal (50) and is diagnostic for Cushings... lol. Most doctors want 3 tests that prove. Good luck with your testing! Keep us posted! Pre surgery... I bought a pass to the Gym. I tried to work out (at the insistence of my doctor). I thought the man was a nut, but I tried. I was so frustrated that I could only lift 20 lbs or less with the machines. Tonight at 6 months post op, I can lift 100lbs with my legs now (I've was too chicken to try the arms!) For me, that was the measure. People tell me I look so much better, but I needed a measureable result, one I could really relate to. It took me 6 months to feel more like myself! Keep pushing for answers! Minnie |
