Is it normal for sensory symptoms become more noticeable after a diagnosis?

I was recently diagnosed with Asperger's (well, grade 1 autism). I've always been very introverted, and not great at social interaction. But academically I've always done well; Good memory, accelerated learning, and well, since I was 9 years old, I've had very advanced knowledge for my age, and even now at 14, I understand some neuroscience principles

That said, for as long as I can remember, I've never focused on sensory issues. Yes, I perceived discomfort from noises, and my reaction was simply to avoid them, without dwelling on them too much.

Unlike now, since I received the diagnosis, I feel that the discomfort is becoming more noticeable: ringing in my ears, headaches, and even sensory meltdowns.

I guess its because I now know about my diagnosis and am more aware of those kinds of things.

But I still have questions; is this normal? Did they intensify with time and/or diagnosis?
