For several weeks, i have had strange itchy red bumps on my elbows that eventually spread to my arms. now it has appearred on my knees and it is spreading down towards my feet. everytime i get these bumps wet, they become sticky and slimy, and the bumps get bigger. they do not look like ingrown hairs, and i still have hair growing on those areas. also, i have found myself constantly having to move my legs to get rid of an uncomfortable sensation in my legs. i am almost 18 years old, and i want to know what these bumbs are before my birthday in september. please, can you help?
