Only slightly pinker next my skin color. Sometimes it itches. Also if is accidently hit one beside something (like i hit my put money on one on the wall on accident) it stings for a minute. Ive have it for resembling 4 years AND IT WONT GO AWAY! Its mode of scare me a bit because its grown a tiny bit overthe four years but not too much. What is it? Should i verbs. Will it grow backbone if i carry it removed? Help!
