Pain hypersensitivity and muscle pain

I have a nonexistent pain tolerance and awful muscle pain from exercise, that probably shouldn't be this overbearing to regular people.

All I get is just the usual "no pain no gain" bullshit and a pain so overpowering it temporarily disables me. Tried some gel for this kind of pain, does not seem to work for me for this exact pain. It seems I have some variation of the usual collagen-related disorder most other autistic people also have.
