Allergy in entire body. Should we do?

My friend got an abortion through MTP on 1 December 2017. She got bleeding on 1st February. It lasted for one day only. Her periods resumed from 28th February and lasted till 5th March. She told me that she got itching on her entire body on 6th March. The itching was persistent since few days. She also had a frequent urge to urinate and orange coloured urine in the month of January. We did urine culture test but, the result was Sterile. But, my friend was still feeling the same. So, doctor gave her CEFTUM 500 for about 5-7 days. We went to a Gynaecologist to rule out the possibility of ramanents inside the body. She said since her periods resumed it's unlikely to consider anything's left. She suggested us to do USG TVS. The results are clear. I am affraid whether the skin allergy my friend is facing is related to abortion or, She is having any disease? Please, let me know what are the chances of having cancer after all this? What should we do? Please, help!
