About two months I got some sort of infection. Tons of yellow mucus, feeling worse, etc. After a few days everything got somewhat better, but the mucous has stayed ever since. At times it was just coming out once a day or so, then went away for a few days after a week of doxycyline, but has since come back with a vengeance. Three weeks ago I had an episode of being unable to breathe even while laying down on my "good" side. My hands and fingernails turned blue, face turned white, and I felt pretty horrible. It slowly got better after sitting up slumped over for an hour or so. Using a pulse oximeter a few days ago showed that my oxygen levels often drop, especially when laying down, though typically my pulse rises to compensate. More observation has indicated that this dropping oxygen is triggered by prior over-exertion, starting immediately after the exertion, and can last for hours or days. 2-3 weeks ago I noticed a new short stretch mark (blue) high on the left side of my abdomen. My abdomen seems chronically swollen, but I'm fat so it's hard to tell 4-5 days ago my right elbow and right ankle joint got very painful. This has diminished somewhat, but they still feel stiff and a bit sore. I thought this might have been triggered by some over-enthusiastic gardening, but it's lasted too long, and it's odd that it's just the joints and not the muscles. 3 days ago my stomach was hurting quite badly. I had some constipation, but not the usual PEM constipation I'm prone to get. Stomach didn't feel any better after the constipation was resolved. It finally got better about 24 hours ago. My appetite was very poor yesterday. My throat has been sorer than usual for the past two days. Yesterday my mucus was mostly yellow, but some greenish stuff appeared as well. Today there's been both yellow and green mucus, but the green is now more intense. Today I noticed a ton of petechiae on my entire abdomen, but nowhere else (aside from a few scattered ones I always have). They aren't tightly clustered at all, but spread out pretty evenly. I have a referral to a cardiologist coming up for the breathing problems, and a sample of my snot went to the hospital to get cultured yesterday. Lung function and x-ray are normal. CRP is slightly elevated, ESR is 31 (I'm usually around 20), and ALAT is a bit elevated as of June 26th. Hemoglobin, glucose, TSH, GGT, NT-pro BNP, D-dimer, and leukocytes + differential are normal as of June 26th.
