Trimming the hair and coming out of ihraam

I live in Saudi Arabia. I performed Umrah one week ago, when it comes to do qasr or halq, I got pain in on the side of my foot. I reached quickly at the barber shop, they were closing shop due to prayer. I insisted but they refused to cut, they instead cut some hair from the upper side and another person with me also done it. After Prayer I wanted to cut my hair further, but due to much pain in the foot I could not go there. Then some one told me it is necessary to cut quarter of the head but I could not do it, now i'm back at home, and was thinking about it, either that qasr is enough for me or not, so my question is was this act enough to become halaal or not? If not, what do I have to do right now?
