Hi Frankie's Mum! Hope you're doing okay. These lumps are interesting. Lumps come in two main categories; neoplastic (cancer) and inflammatory. This looks like a very miniature version of a flat, disc-like inflammatory reaction called urticaria, but I've never seen urticaria so small; typically they'd cover more area, like a small counter, or an old ha'penny. Another possibility is an inflammatory reaction to something in the hair follicle, so-called 'folliculitis.' Folliculitis is a symptom not a diagnosis and can be linked to demodex mites, other kinds of mite or (often immune-mediated) change within the follicle (allergy, flea and mite reaction and so on). Sometimes (eg if no mites are involved and the allergen doesn't stick around) it just goes away on its own, but other times it can stick around and it pays to find out what is causing it. Have you seen your vet yet? I don't think folliculitis, urticaria or mites (or evwn cancer) would respond to putting cream on; if using vet prescribed flea and demodex treatment, its worth making sure that this is up to date. If the lumps don't go away on their own in a few days, or if they start getting worse or bothering their owner, then a vet visit for trial treatment or diagnosis sounds like a good idea.
