I have had a red flush across my face for some time but it is a flat rash (was investigated for Lupus after a positive ANA but all other tests came back negative). Now though I have had angry red bumps (they have no head so not spots as such) come up on my face and head. They come up and then flatten the next day or so but leave a small brownish purple mark which as yet haven't disappeared. Some of them have then re-emerged as red bumps but not all. I saw a dermatologist for the redness before the bumps came up (a few weeks ago) who just said use antibiotics when the pimples come up but at that point I hadn't had any pimples - was not impressed - and they aren't pimples now, just bumps! Plus I used antibiotics for three months and it didn't make any difference. Anyone got any idea what it could be - or is it a form of rosacea?
