A common foot condition know as sinus tarsitis can cause acute and eventually chronic foot pain if not diagnosed and treated promptly. The sinus tarsi is an opening in the outside (Lateral) part of the foot between the ankle and heel bone. Injury to this area can be due to an inversion sprain or severe overpronation. Personally I have suffered from this condition for the past two months. I have a flexible flatfoot deformity which I was born with but have been able to participate in sports and running with the help of custom foot orthotics and an anti-pronation running shoe.
Typically patients presents with pain localized in the sinus tarsi area with swelling. X-rays, ultrasound, and MRI can help to diagnose this condition along with clinical findings. Personally I have been training for a 1/2 Marathon and have been running more frequently and longer distances over the past few months. My acute pain started suddenly in the sinus tarsi region. X-rays were negative. I iced, cross trained, tooks NSAIDS, and immobilized my foot in a walking boot for two weeks. My pain improved slowly so I had a MRI ordered which showed inflammation with swelling in the sinus tarsi region.
It is very important to recognize foot and ankle pain that doesn't go away after 5-7 days. Conservative treatment is very helpful if this condition is diagnosed early and promptly. At Carolina Foot Specialists we have in house diagnostic digital x-rays and ultrasound along with having experience in athletics. This combination allows our practice to understand what are patients go through with these type of injuries since we have experience most of them first hand. We follow the philosophy of not just stopping all activity if you have foot pain we like to advocate alternate exercise routines while you are healing from your specific foot injury.
