Thank you doctor for your response.
I will eventually get it check out.
Hello,
If the purple spot is raised then the possibility of lichen planus needs to be ruled out . if it is under the skin then a bruise needs to be ruled out which is formed because of trapped blood under the skin. The blood under the skin which causes the discoloration of bruising should be totally reabsorbed by the body in three weeks or less.
If it persists then it may be due to formation of hematoma because of blood trapped in tissues. This blood may need to be drained.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
