Yet, at ER last night, the finger reader showed 100% oxygenation even tho my breathing was a bit laboured. so, I didn't get oxygen. So, if I am oxygenating well, why do I find myself short of breath still? It's a very slight effort to breathe compared to normal usual automatic breathing. Started last night when I took 15 mg's of restoril within 40 min's of taking a percoset. Felt like the drugs maybe relaxed my lungs TOO much, or maybe was an allergic reaction or something. Anyone know what's going on, or experience this before? Doc at ER hadn't a clue, tho he was reasonably nice. if anyone has experienced this, how long til it got better? I am afraid to take the percoset now and my sleeping pill at night, though I obviously will be more careful to separate them by 2 hrs like I have been doing before. Also, I took more of the demi-percoset yesterday than i have yet to date [max dose] due to more extreme neck pain [I carried home shopping and was in my worst position for a while for a treatement] I am afraid to take Benedryl or chlortriplon cause of their sedating effects, in case my lungs were too sedated or something. Am I making any sense to anyone? Please help me, this is a bit worrisome, but obvioulsy I don't have any blood pressure concerns/oxygenation concerns or they would have picked that up at ER. Thanks.
