"dx'd late 2005. Started Gleevec, sick as a dog, got over that but was very hard on my stomach. In remission 2007. Bone and joint pain bad. Cramps in ribs. 2013 started Sprycel. No nausea but bone and joint pain. 2015 at dr complaining short of breath. Tests all normal. 2017 in hospital twice from getting severe infection from other immunos for PsA. Resting sats high 80s low 90s and pleural effusion. Second time effusion worse than the month before. Not enough to drain but still short of breath, low sats at rest. Finally decided it's the Sprycel so back on Gleevec. Been off Sprycel for a month.  Am feeling much better but sats still very low.  If any of you had low sats, how long after stopping Sprycel before you got better?"
