I have Sjogren s, R.A., and Lupus. I have swelling everywhere, but in my left foot it is severe. I have low BP but have put on a lot of weight since they started me on steroids. From my lower shin down, there is almost no feeling. The swelling worsens throughout the day, to the point I can t fit a shoe on my foot. The top of my foot is the most swollen. The swelling is worse all on my left side, but the foot is just horrible. They have run test after test trying to determine the cause, with no success. I am on gabapentin, plaquenil, prednisone, methotrexate, tramadol, Tylenol 3, and furosemide. I have a very high white cell count, and very low lymphocyte count. I see random doctors at a free clinic that is attached to a med school. The latest doctor today looked at my foot, said well it must be from your smoking, ordered one full panel blood lab, and sent me home. I do still smoke, but maybe 3-5 cigarettes a day. Could the smoking actually cause the swelling and stabbing pain that runs up my legs into my hips and back? The pain is severe enough that it greatly limits my mobility.
