What happens if I don’t “feel anything” after a Reiki session?

Spiritual energy is powerful. If you do not feel anything after one or two sessions, it's probably because the practitioner's work. How long has it been? Have emotions come up for you? Do you feel clearer? Lighter? Foggier? Pain? Diminished pain?

It is very important to ask your practitioner before a session-
1. Where are they channeling the energy from?
2. What are their goals?
3. Where did they learn these practices?

Every practitioner works on a different plane of consciousness, therefore some practitioners are way more powerful than others based on their level of Soul initiations, consciousness and practices in this life.

Even if a practitioner is working on your etheric layers, you will feel it in the physical consciousness. This is the laws of physics and goes back to spiritual scientific teachings.

That is very normal and not everyone will have the same reaction. This universal energy that is channeled through your practitioner is working on both physical and spiritual planes, it is not linear, so even though you don't physical feel it doesn't mean it isn't working. Energy healing is also cumulative so it can take multiple sessions for the energy to release/open any blocks. Each session is specialized to each individual's needs, so each reaction during and after will be different. I hope this helps! :)

Sounds like it didn't work. From my experience the patient should feel lighter. Perhaps try another provider or modality.

There are some people who don’t feel an immediate change after a Reiki session, and
it’s nothing to worry about. It doesn't mean that it hasn't “worked,” just that it's taking
longer for energy to settle in. Ideally, you want to give yourself a little space after a
session to let it integrate: take this time to drink some water, stretch, walk, or nap if you want. Often people notice that they feel better later on in the day, or when they wake the next morning.
