Thank you. A change was made in my medication for Parkinson disease which I ve had since 2008. I had been taking ordenary carbidopa/levadopa 23/100, but my neurologist wanted me to try the Controlled Release type. I started having a problem taking a deep breath and yawning, and in checking out info regarding this new med, it lists bizarre breathing problems as a possible side-effect. This matches my symptoms, for sure, but I was wondering what the considered a bizarre breathing problem. I even had to go to the ER two nights ago as it was getting really bad. After doing all kinds of tests there, they said they couldn t find any serious problem (with heart, lung, etc.) They did find I have a UTI and prescribed med for that. But they didn t help me with the breathing problem. So any info you could offer would be greatly appreciated.
