I keep getting these itchy bumps on my face, neck and chest, just one or two usually at a time. They come up like a red lump which is intensely itchy, almost like an insect bite, but I'm fairly sure they are not bites as I get them all year round. I have tried taking antihistamines and applying Benadryl cream or hydrocortizone cream but they do not go away for about a week. They don't come to a head and don't have pus in them. More like fluid filled lumps and leave a scar behind because I have tended to scratch them in my sleep. Does anyone have any idea what they could be and is there anything I can do to stop them coming? I just seem to be getting rid of one. when one or more appears, and they are really noticeable because I have very pale skin. This is really getting me down, so I would appreciate any help.
