Hip Flexors and husband.

Still fighting with them. They hurt when I workout and if I do not workout they hurt when I don't along with the knee. I thought I had this under control. Beginning to hurt even lying down. What can it be? What am I doing wrong. Is there another tear that is getting worse without diagnosis? It feels as if someone is rotating my kneecap. I guess I could handle the hip pain but not the knees. They prevent me from doing what I want to do. When is this nightmare going to end. I am sick of hearing my husband say it is in my head and that it is depression. Can someone please give me advice on how to answer him without killing him. This is the same guy that cannot take any pain. God forbid if anything takes away from his workout and competitiveness with his younger cousins. He is getting ready for ski season and I am already sick of hearing about his routine in the gym preparing for it.
