Hi I m male 19 years old, 5 8 , weigh 128 pounds. I really am not allergic to any medicine, pets or food. Four days ago I went to the beach, and got a bit sunburned but that s in the shoulders, used to be the only thing bothering me at the time, but later that night I had like to little red bumbs in my ribcage (far from where I got sunburned), they itched and didn t really hurt to the touch or felt tender, the next day those 2 red small itchy bumps became like 6 and now I have so many red little bumps itching and they are all close together and some are separated but at a relatively close distance. Some are alone and other ones are in groups as well but smaller. And now the main ones that grew/itched first are more tender to the tough and hurt a bit if I apply pressure . Not sure if this is Dermatitis ( eczema ) but yeah my skin hasn t gone rough or hard, it s actually quite soft/tender. But yes, I don t want it to keep spreading as it seems it s what it is bound to do the next days. And this is the first time I have ever had any type of rash in the chest area.. I did get jock itch like 5 months ago... but compared to the pictures of it online mine were like nothing, like my jock itch and the rash I have right now on my ribcage they really don t look as critical as many pics dpict online, but still they show their symptoms. Any help?? If I could include pictures it would help I think a lot more.. do you guys have that option? If not, should be considered to be added. Anyways umm yeah that s all thanks for the help.
