Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
Normally the abrasions from itching heal quickly in 2-4 days. However if the same has persisted beyond that time then it is likely that you are having a add on bacterial or fungal infection
. You should start yourself on some antibiotics like cefexime for 3-5 days and keep the area dry and clean. In India the antibiotic will cost you Rs 100.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
