Thanks for writing in.
The condition can be papular urticaria
or erythema nodosum
A visit to dermatologist
will allow proper assessment of severity of condition and allow prescription medicines.You can take tab.cetirizine
once a day for itching.
Also you can apply soothing lotion like calamine lotion twice/thrice a day.
Hope this helps.
I will be available for any further clarification you need.
