I’ve suffered from lower back pain for over 10 years but it is getting much worse and I am not getting any help from GP. The pain often wakes me during the night and make getting up and walking after waking difficult and painful. The pain lessons after an hour or so but discomfort frequently returns during the day. I go to gym and swim twice per week, Pilates and yoga every week. I have good flexibility, can put palms on floor with straight leg bend. I’ve had a lumber X-ray which showed some deterioration but apart from exercises (which I do) I am not getting any help or diagnosis from GP. I can’t take nsaid painkillers because of hiatus hernia. I am concerned that perhaps this constant back ache might be related to problems with internal organs, uterus or o eries etc. I’ve only been examined for this problem by surgery physiotherapist. Would cancer of spine show on lumber X-ray? I would appreciate any comments.
