Mind full Meditation

I Have been training third eye meditation for past three months,now the tingling sensation on my forehead never goes off and i couldn't go proceed and thought of trying mind full meditation,where we see everything in bare sense of view and i found about Buddha's teaching, i found it very interesting,and found some basics to start mind full meditation where they have said to keep my mind on raising and falling of abdomen during breathing.Which they told would help us realizing nothing is permanent and we should mind fully note everything that happens when we breath.this was basic. NOW THE PROBLEM IS MY FOREHEAD SENSATION IS ALWAYS THEIR MAKING MY MEDITATION TASK TOUGH.
