Lill, my youngest daughter had one on her leg at birth. She had it removed at age 10 because a biopsy showed pure cancerous cells, and the doc said sometimes puberty hormones could trigger changes that might end up cancerous. Hers was not red but instead brown and skin tone mixture.
My granddaughter has CMTC, a vascular disorder on her left leg. We can't pronounce the name so we just say birthmark to her. They visible vein's wrap all around her leg, thigh to ankle. She's only 9 and says kids are teasing her. I suggested to her mom to help her do a school writing project to educate the other kids. Her doc says hopefully it won't cause any problems, other than that leg was much smaller at birth and required her to wear a brace and have PT to strengthen it.
Is there a reason they couldn't get it off your neck? I'm guessing you mean it bothers you emotionally but if I'm wrong just correct me. Are you able to camouflage it with makeup or wear neck scarves? You should know it doesn't define who you are. I know it seems easy for me to say, not having one. But I mean that in the most affectionate and compassionate way. God makes no mistakes, and He uses us and our situations to help others going through similar things.
When I was told to use a walking cane or walker by my neurologist I laughed and said "yeah right!" I'm 53 and thought there's no way I'm going in public on a cane or walker at my age. Little did I know how fast my imbalance and weakness was going to grab hold of my body. At first I got real funny and sometimes judgmental looks. But then small children began noticing and asking "what's that for?" In their innocent question I was able to let them know it was because I might fall, and hopefully teach them not to treat others who are physically challenged or different any different than they want to be treated. Of course their parents looked embarrassed but I just smiled at them. As my grandmother use to say, "Physical beauty is only skin deep, but ugly goes to the bone. Be beautiful in your heart and you'll never be ugly, even when you're old and gray." She said it with a twinkle in her eyes and a smile on her face. 🙏🌼
