small red spots, started on right leg, I first thought an insect bite, they are not. two or three - in a row, started Fri. 7/23, now more on right leg and few on left and two or three on each arm, -by shoulder and arm pit. Start out bright red, almost a white circle around and within 24 hours, red spreads and looks like a bruise, small itching starts a few hours into appearance. Spots are not hot , do not seep, a bit raised, after several hours. Initial spot is the size of the head of a common pin as I use in sewing. Does not look like a bite/no center hole from the intruder/ a center appears as the spot grows larger and color changes. I have no medical conditions, I take no prescriptions, I have had one orthoscopic knee procedure to repair torn meniscus-5 yrs ago. Haven t been out of the country. Noticed a couple red spots after a shower, then attended a family reunion at a St Park Grp. Camp and watched them spread and more develop. No fever. I am home and now have about a dozen spots. What am I dealing with and what kind of doctor should I see?
