Haha yeah I know what you mean. Though I sometimes seem to have sub standard pain responses, I can go the other way with some things. I guess it's all part of the sensory stimuli package. Like sometimes I can hear fine, but then other times every noise is so loud I feel like my brain is about to explode, and sometimes things seem so quiet I'm not even sure if I'm hearing them at all. All of that is connected through the nervous system, so it makes sense that if one of them fluctuates, they all could.
