Sick and symptoms!

I have nothing cute and clever to say today. Maybe tomorrow I'll have energy to write. I've actually been feeling rather poorly and Monday/Tuesday were high drama over here (including sad goodbyes, parades, and eroded pipes) to be elaborated on further at a future date. For now I am trying to decide whether to try to hunt down a doctor or not.
For the last week my muscles have felt very weak and sore despite only minimal exercise (and no strength training and nothing new). Then just recently I have had flank pain, lethargy, nausea, low-grade fever, itching, and dermatological effects (petechae, rashes, eczema). I know it sounds absurd but I suspect myositis or myopathy for some reason, with resulting stress to my kidneys.
I do not take any medications and I have not been sick recently, but I do have a history of thyroid disease. That's really the only cause I can think of! I know I have to go to work tomorrow because I couldn't get coverage on such short notice, but if I do not start feeling better I will call my doctor. Unfortunately the last time I called her (years ago) it took over six weeks to get an appointment, so I don't have high hopes. Maybe my symptoms resolve without treatment!
In good news today, I got THREE packages in the mail, a pair of Banana Republic pants I bought on Ebay (the discontinued Ryan style, my favorite! I snap up every pair I see on Ebay!), a huge box of canning jars (I want to preserve some of the citrus while it is on sale at low winter prices), and one of the pairs of running shorts I bought on sale. They will be replacing running shorts I bought when I was sixteen years old and simply have to throw out because the elastic is so dead that they don't stay up. They've definitely done their duty, though!
How long do your workout clothes usually last? Besides these shorts, I also had some "Everlast" jog bras that I had for eight years!
