Generally, you can't tell if you have a subluxation on your own.
Subluxations, or spinal nerve pressure created by misaligned spinal bones, can be likened to a dental cavity. Dental cavities can develop over time without you noticing and will impact your oral hygiene. The same goes with a subluxation in your spine affecting your nerve system and spinal hygiene.
Just like how people visit dentists to support oral hygiene and identify/correct cavities - People visit Chiropractors to support spinal hygiene and identify/correct subluxations.
That is similar to Chiropractors checking your spine for subluxations. Chiropractors are highly trained in supporting your spinal hygiene and identify/correct problems developing in your spine.
However, with regular Chiropractic care people often become very spine conscious and are much more able to identify obvious subluxations in their spines.
Being more in tune with your body is a great thing and allows you to work towards a longer, more comfortable, and active life.
Some subluxations are not obvious and slowly progress over time.
