I'm curious as to what weird side-effects that people get though their medical history, and no I don't mean something like "I took this medicine and I had anal leakage". I mean something like mine.
I've had asthma since I was 5 years old and as a result I had to take shots to combat it at first it was just two once a week then when I was about 10 or 11 a new shot came out and my shots increased to 5 a week (all on the same day). As a result of having to take all of those shots since I was 5 caused a build up of scar tissue in my upper arms and the results of that are pretty cool to me; first thing that is a side effect is my upper arms are almost rock hard, if someone goes to punch me it hurts them and hardly hurts me at all. the second thing is because of the scar tissue I use my arms to hear slightly. For instance when they would stick the needle in my arm I could hear the liquid moving in the needle and if i touch a running faucet I can hear that as well.
So, what's your weird side-effect?
