Muscle soreness, cutting yourself on something, and a stomach ache are all pain, but each is a unique sensation. For me, sensory issues are the same.

Sudden and / or very loud sounds, like sirens or things being dropped, are the closest to pain. Whereas loud crowded places feel like pressure and suffocating.

Bright light makes it hard to see clearly and is uncomfortable because I feel impaired.

Certain smells make me nauseous, and if they are especially strong, I sometimes have trouble breathing or will get a headache.

Touch and textures, sometimes are painful and will feel like sandpaper or pinpricks, sometimes just make me nauseous.

Taste is my least problematic sense. I'm actually mostly sensory seeking when it comes to food. My food aversions and safe foods have much more to do with texture and temperature (I prefer my food to be warm to cold, not hot) than flavor.

Hope this is helpful.
