How do you know you have a psychic block? What is it that you're even referring to as a psychic block? Are your only signs and symptoms that your spells don't manifest? What other phenomena do you notice?
If you think you have an energetic block, then by all means go visit an acupuncturist, although most people aren't aware of this phenomenon either.
Perhaps something else is going wrong with your casting, something unrelated to psychic/energetic blocks.
