I am a 16 year old female, and have recently visited sub Saharan Africa. I have had skin issues in the past, as well as rosacea. About 3 weeks ago my stomach and inner thighs became extremely itchy. Soon small red dots appeared on my stomach ( all the way down to my pubic hair), followed by dots on my inner thighs. Many of the dots have now gotten bigger and one of the ones on my thighs is raised. I also have several patches of dry almost scale like skin ( one of them is ring shaped), although this could be caused by the dryness ( it is winter here and around - 30) Does anyone know what this could be?
