Tiny bumps/rashes and antibiotics

Hi, I was having persistent tiny itchy bump/pimples.rashes appearing at different times and various part of the body, limbs, hands, fingers and later stages in the scalp. Have gone to a few skin specialists but all diagnosed that I am old (I am 68)and at the age where I have dry skin and skin eczema. One specialist even diagnosed that I may have pet mites and allergy pets; then on subsequent sessions said I have human mites and prescribed Aoscabs Lotion treatment but none of these over the months ever help. Finally, consulted with an another specialist he said all the earlier conclusions were and that I have dry skin and at my age it is expected to have this. His prescription was to use plenty of QV kin lotion, use Cetaphil cleanser instead of normal soap and apply the Beprosone ointment whenever the itchy bumps/pimples appear. Have been using these for one and half years but the itchy bumps continual to appear. After months of living with these I met a friend who said that his sister has the same problem and took antibiotics and she has recovered fully. Out of desperation or vanity (cos my scalp was having bumps and it looks terrible), I decided to consult a doctor and request for antibiotics. Was given Betamox for 5 days. I could feel the difference even after two days taking the antibiotics. By the end of the course, the itchy pimples/bumps in my scalp has dried up and gone and so do the those on the rest of the body too. It was such a relief and I could sleep better with the itching. It is already about 2 weeks since and no sign of the bump/pimple/rashes. However. I am starting to see one or two appearing. Firstly, I really like to find out what is the root cause. Secondly, even without the root cause, I would like to ask whether I can or should start another course of antibiotics. If yes, should it be Betamox 500mg or something else. Your advice

Hello. Thank you for your inquiries.

First and foremost, we truly understand your concerns regarding on your itchy bumps on your scalp and other parts of your body that have been going on. You have informed that you have been using a few product and medications to treat your current problem.

For your information, papular/vesicular itchy rashes on the scalp has a wide range of diagnosis that can be concluded. It is best to be consulted after a good visual examination of your skin problem by an attending dermatologist. However, we might have some general idea regarding your problem:

  • Contact or seborrheic dermatitis. May be caused of an overeactive immune response or an allergic reaction
  • Actinic keratoses
  • A skin infection called Mosculum Contagiosum, which causes raised bumps or lesions.
  • Lichen planus is an autoimmune disorder caused by viral infections, allergens, stress or may be due to genetics. They are described as itchy purplish lesions or bumps and blisters or crusts may be present.
  • Seborrheic dermatitis may appear as a reddish rash with greasy yellow crust.
  • Itching bumpy sores can be caused by a bacterial infection. This may lead into two things: folliculits or impetigo.
  • Follculitis is the bacterial infection of damaged hair follicles. This may be caused by excessive plucking or shaving of the hair, frequent touching of the scalp, or having a hot or damp skin all over the time.
  • Impetigo is a skin infection by a bacteria called streptococcus. This bacteria may infect the skin dermal layer by any previous skin injury.
  • Herpes zoster or shingles is a known adulthood skin condition. They are caused by a previous viral infection of the same which caused the chickenpox.

We assume that whatever skin condition you are experiencing has to be related with a bacterial infection, given of your past history of using Betamox, an antibiotic. Betamox is an antibiotic medication to treat streptococcus or staphylococcus infection. However, you are aware that the antibiotic efficacy on your condition is lesser by the day. This is maybe due to a bacterial resistance that may develop overtime towards said medication.

Hence, we suggest you to meet your nearest doctor and present your medical and health history thoroughly so they can give the best solution on your problem.

We assure you that our conversations are kept in confidentiality unless additional consultation needed with other medical parties. Thank you.
