Is it dangerous to focus on ticks from childhood during meditation?

At the panditarama vipassana retreat they ask us to focus and observe on the object that pops up our attention, such as a pain or thought. I started having ticks that I had on my childhood, such as closing and opening my right eye intermittently very fast. The tick does not stop if I observe it, and it does stop if I focus on something else, such as the rise and falling of the abdomen. Is it dangerous to continue focusing on the tick? Will it then appear in my life when not practicing meditation?
