What Causes Rashes On The Knees?
Does not seem like allergic reaction. Some more information is needed.
Detailed Answer:
Hello,
Thank you for asking at healthcaremagic.
I carefully read your question and checked the uploaded picture also and i understand your concern.
Allergic reaction may cause different types of skin rash but the one your child has developed does not seem typical of it, even though it can not be said for 100% that it is not allergic.
There is some more information that might be very helpful to better know the cause of the rash.
For how long has the child had this rash? Is is getting better or worse or the same?
Does he have other symptoms like fever, fatigue, etc.
Does anyone else at home have similar rash?
Is he otherwise eating and playful as usual?
The cream the dermatologist will help with any skin lesion by reducing inflammation so using it might help and does not seem to cause important side effects so I would say you can go on with it but if no improvement in 4-5 days than it is obvious it is not helping and does not seem beneficial to be used further.
Please let me know of the information above. I hope to hear from you soon.
Kind regards,

It is not likely that you have infected him- please see the details
Detailed Answer:
Hello, again,
Thank you for replying and giving more information.
It is great that your son is active and playful as usual, this makes infection less likely as the cause of the lesions.
Dermatitis in itself is not contagious so it is unlikely you have passed that on him. Sometimes the tendency to develop allergic reactions might be inherited but not the allergies themselves. This means that if a parent develops eczema or dermatitis, his/her offspring might have a higher risk to develop it also but is not 100% and is not necessarily the same type.
By the pictures also I think they seem more like insect bites, very likely mosquitoes, but the best way to know this is by observing them in the coming days. Normally a mosquito bite should heal within a week, he might get new ones but generally they happen in exposed areas like legs, arms and face and it is ok.
Please make sure you have proper protection against insects, having a bed net to protect him at night is advisable. There are insect repellents that will help reduce bites, etc. If the child feels he wants to scratch the lesions than local cold compresses reduce the itchiness.
I would also recommend you to continue using the cream your doctor already gave you.
If no improvement in the next 4-5 days or you see that your child is worsening or having fever, fatigue or any complaints than he will need to be seen by a doctor.
I hope this is helpful and answers to your question but please feel free to write me in case more clarification is needed on this.
