Two weeks ago I noticed a small area of spots on my shoulder and on my wrist. I saw the doctor who prescribed me with locid cream and rezene tablets to stop the itching and calm the area down.
I'm still getting small, what appear to be bite marks, over my arms and wrist and the cream and tablets are not helping. The spot first appears swollen and itchy, then the swelling goes down and the area forms a little spot.
I went to another doctor who on examination said it might be scabies so I used some lotion but I'm still getting spots on my arms and wrists.
I'm currently travelling at the moment so I'm not staying in one place so have ruled out bed bugs. I do check the bed where I stay and it always appears clean. I have washed everything I use on finding the marks so I don't think I'm travelling with anything.
Can you advice what it could be? I thought it was eczema until the creams prescribed did not work.
Many thanks, Liz

Hi Liz, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the spots, some blisters and some that are close to form a bubble on shoulder and the wrist along with itching in the affected area.
Scabies appears as red bumps, blisters and later scaling, mostly between fingers and toes, on inner sides of the wrists, in the skin folds, or anywhere on the body.
The marks that you describe might be S-shaped tracks in the skin(superficial burrows by the scabies mite) often accompanied by small, insect-type bites called nodules that may look like pimples. The treatment of scabies is with overnight application of permethrin ointment but itching can take a month to heal. So you can try repeat application of permethrin after a week and take rezine for itching and consult with your dermatologist for definitive diagnosis as the same cannot be made online.
Hope this helps. Take care.
