Question: I have been having some numbness in my left leg for quite some time now. I go to a chiropractor and getting my neck and back adjusted helps but doesn't last long. X-rays have shown that I have an old fracture in both my lower back and one in my neck. I try to walk 10,000 steps per day, but average closer to 7,500 on most days. Tonight my left leg has some numbness and so does my left foot and there is some swelling, too. I am elevating my leg. Is there something else I should be doing?

Thank you Doctor Spaho. It looks normal this morning, but I will do some follow-up and see my regular doctor. I am getting ready to travel internationally in July and I am always concerned about the possibility of DVT when going on long flights. There is a company called Lifeline Screening that operates in my area. They advertise that they find problems with blood flow in various areas of the body. I like their screenings because they are fast and you get the results almost immediately. They are also less expensive than other options. Have you heard of them and, if so, do you think they do a good job of identifying potential problems? I sit at a desk a lot at work and I think this may have led to some of the discomfort I am experiencing. I do get up and walk around several times during the day, but I suspect not often enough. Is there anything I can do to prevent DVT from forming and becoming a major problem in the future?
