I've had these for well over half a year now and I'm wodering if I can remove them.

They are a dark red purpley colour and slighty raised, they're on my right calf. They are shaped in lines going down my leg.

Do you still have these marks? I have red marks on my calves (and entire legs) as well... my doctor believes it was due to a 'drug eruption'... I have been hopped up on all sorts or otc meds due to my allergies...
