I am struggling for 4 years about this red patches found on my arm. When I exposed to sun it increases but it is not itchy & not wounded, a tiny red patch that has a blood clot. I have been consulted the dermatologist & other physician but until now no recommended medication & findings, several laboratories has been tested but everything is normal. I don't know what is the cause of this. Please pray for my healing brothers & sisters. Thank you so much. God Bless you all.
