I have a ton of these things. I used to think they were inflamed and knotted muscles, but my massage therapist tells me otherwise. I have a hard time telling which lumps are lipomas and which ones are myofascial trigger points, especially since most of them are in my back, so I'm not sure if any of mine are painful.
Humidity. The most common cause of condensation on double-glazed windows is humidity. The outside window is colder than the inside window causing fog or frost to build up in-between the two panes. The window and house is extremely airtight and cannot breath.
Many British traditional homes, especially Victorian cottages, have been mutilated by the appearance of uPVC windows. It is not necessary to fit double-glazing in order to prevent heat loss; secondary glazing (much cheaper) and thick curtains combined will do an excellent job.f condensation appears on a double glazed window; it does not mean that the window is at fault; in most cases, it is high humidity in the home. A better suggestion would be to see how high the humidity is in your home and things like placing plants on windows sills are a contributor as well.
