Hello. Thank you for posting your query at DoctorSpring.com
I understand your concern.
Hip can bruise really easily, since there are a lot of muscles in the hip, and also the bone is in very close proximity. Hence contusion is very easy, and also it takes a long time to heal. It takes time to develop into a full blown contusion, since the muscles are also pretty large, and it spreads to the entire length of muscle. If possible kindly upload a picture.
If you're having no difficulty in movement, or moving laterally to be more precise, then there is nothing to worry about. Immediately after bruising we should apply ice to the bruise several times a day. If that is not done, bruise can turn really big. Since its already been a week, i will advise you to just take a cloth which is nice and warm ( keep it dipped in warm water for some time ), and apply to the area. It can be done 4-5 times a day. This will enahce faster healing. Also an anti-inflammatory spray like Relispray ( or any OTC brand available locally ) can be applied on that area directly. Additionally if there is too much pain, you can take Tab. Ibuprofen 400 mg up to twice daily, after food to relieve the pain. As i said before, if your movement is fine then there is absolutely no reason to worry about.
Feel free to discuss further,
