Magick tattoos are to be chosen very carefully. Some symbols just shouldn't be on the body permanently or at all. If it is causing you trouble, I suggest doing more research on the symbol and find a way to counterbalance it with another symbol or remove it all together. Test counterbalancing symbols by drawing them on yourself with something washable, I would use waterproof liquid eyeliner.
Where the tattoo is located will also have meaning. Various parts of the body are connected to different keys to emotional and mental influencement.
Ok, opening up my grimoire....
The arms are a symbol of protection, strength, action, energy, divine nature, and accomplishment.
On our right arm would influence what we put out (our actions and energy). The right arm/hand is an extension of the will and of intention. On our left arm, it would influence us inwardly (emotions and thoughts) because this is our receptive side.
The ankle is a sexual symbol and is also associated with transcendence
Shoulder is a symbol of strength and power.
Just a quick note,
By putting a symbol into our skin, we are negating the protection that our skin represents. By having ourself tattooed, we accept that symbol's energy into our bodies, allowing it to effect us fully spiritually. Most magickal tattoos are carefully selected and tested with marker, henna, or some other long lasting but easily removed medium. If they work really well for you, over weeks or even months, then you can consider making it a permanent part of your body.
