Welcome to healthcare magic forum
You seem to have developed a fungal infection
of the groin region..Which can be either tinea infection or candidiasis
You should try to keep the groin region clean and dry
Do not apply any kind of oils or moisturizing creams over the groin region
Wear cotton undergarments inorder to reduce sweating.
gel over the affected area twice a day.
Also take oral antifungals like fluconazole
like 150 mg once a week for upto 6 weeks.
And to relieve the itching, take oral antihistamines like levocetrizine once a day .
This infection does not seem to have any relation with the medical abortion
that you just had..
Hope it helps
