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.
Typically the first place condensation can be seen is on window and door glass. Just like your bathroom mirror doesnât cause condensation after a hot shower and your car windows donât cause interior frost in the winter when several passengers are in the vehicle; the cooler surface is where it collects.
