Rash of Itchy Pin-Prick Sized Dots in Foreign Country

I have a rash.  It began on my inner thigh and has now spread to my lower abdomen.  It looks very much like razor burn.  Mostly the small pin-prick size red marks are not raised although if i scratch to much they begin to resemble a mosquito bite.  I am travelling in a foreign country and will not have access to my dermatologist for another 2 weeks.  The itching is unbearable and it has been going on for two weeks (but I have been travelling for months and it only just began).

Concurrently I also got clusters of small raised bumps, tiny blisters that appeared in clusters around the joints of my fingers on both hands.  These also were extremely itchy but are difference in appearance than my rash.  They have been described as 'tapioca-like' by other websites and if scratched they break open, ooze a very small amount of pus and will eventually dry up and peel off.

I have been treating this with skin lotion and hydrocortizone cream to no avail.  I also should mention that I am using a local laundry detergent (this is the only thing I can think that has changed, same body wash as I use at home) that I could have an allergic reaction too.  I'm not sure because I have washed all my clothes with it but the rash is limited to those two areas.  It waxes and wanes with no discernible pattern.  It seems to be most mild in the morning when I wake up and worst after I'm out all day walking around.

I've ruled out scabies based on photos and symptoms.  I have no history of allergy or eczema that I know of.  I have been on accutane for nearly 5 months without too much dry skin but i stopped taking it when the rash started.  Any treatment or even coping mechanism would be helpful until I am able to see my dermatologist.

The rash on my legs looks far worse but the rash on my lower abdomen is far far more itchy.  Also I do not have any on my actual groin or genitalia which i would expect if it was due to washing boxer briefs with the wrong detergent.

It can be dermatitis (atopic, contact, allergic), heat rash or excessive sweating causing sweat dermatitis.
You may try calamine lotion on the rash. You should also maintain hygiene and try to keep the area clean and dry, wear loose-fitting cotton clothing. Also use an antibacterial soap or mild soap like dove.Avoid deodorant / cosmetics. You can also use a barrier cream with zinc oxide paste applied directly to wet skin after bathing. Take some antihistaminic lie Benadryl or Claritin for the itching.

If the rash persists then it will be best to get it evaluated from a dermatologist.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
