I have been having a really hard time getting enough oxygen lately. This has been one of my issues for a long time, but the last few weeks have been worse than ever, to the point that it is starting to really scare me. Of course, getting freaked out does not help, so I am trying to remain calm. I think that it is worsening bc my MCS is also worsening and bc there are fireplaces in all the upstairs apts in my complex. I live downstairs, but I think the fumes are getting into my apt. I have been looking and looking for a place to move (and have also been considering aussiewoman's plans as a possibility - still checking into some things re that - love that she is doing it, though, whether I wind up benefiting, or not). I do know that I am having this problem when I am not at home, though, so the fireplaces are probably not the only reason....actually almost passed out at the store yesterday, bc this was happening and I got really light headed. I do know that the winter weather does not help me, too, so that is probably part of the problem rt now, and I am also looking into getting a humidifier, but the less expensive ones can harbor mold, so I am not sure if I can find one that I can afford and that will be safe. And, I also know that air hunger is a symptom of lyme - would not surprise me if I have that, too, but the tests are so inaccurate and unreliable I have not had one done. Anyway, I am wondering if anyone has any suggestions for dealing with this (the breathing itself and/or the fireplace issue). I already have a very good air purifier in my apt., and I know how to get myself to relax, but like I said, this is getting way worse.....and it is even happening when I am lying down and relaxing. I wound up in the ER from this and related symptoms before, and the oxygen did seem to help a little bit, but I have also read so much about us possibly being oxygen toxic, that i am not sure if that is good to use that often.....and I don't know how to go about getting oxygen anyway, other than the ER. I do have an inhaler for asthma, but this is not asthma so I hesitate to use it for this,and it doesn't help that much anyway, and it does make me feel bad in other ways.
