Growing pains

I'm not sure if this is a sign of aging, or me just being klutzy and forgetful, but I've been randomly finding aches/pain that's cropped out of nowhere. For example, I was getting ready for my walk last night, and I realized my upper arm hurt... like someone had punched me yesterday and I was only just feeling it. It's slightly better today, but I'm wondering what could have caused it.

Today I woke up and noticed my chin had a swollen spot on it, maybe the size of a dime. I've been anxiously applying benzoyl peroxide to it in the event it's a major cyst brewing up to spoil my weekend, because underneath it feels like one. Either that, or I bumped my chin on something and haven't figured out what. (That's happened before... I've hit my forehead on something, found a bump the next day, and immediately applied topical medication to it before I realized it was the aftermath of whacking my head.)

I have noticed that the way I sleep is probably not the best for preventing said aches and pains. Lately I've found myself curling up my hands and arms in weird positions, possibly to keep them warm (bad circulation?), and then I manage to pretzel myself to try and get comfortable. If that's not a sign that I need a new mattress, I don't know what is... but mattresses are mad expensive! Like hundreds of dollars! And apparently you have to haggle with the showroom guys to try and get a good deal. Of all the family traits I inherited from my parents, I didn't get the haggling ability from my father. I did get the cheapness gene from him, though. ;)

Anyway. Back to nervously checking my chin for any signs of possible zit formations...
