Hi There

It is possible that you have one or the other condition, however definitive diagnosis of one or both conditions is difficult due to the complexities of the tarsal tunnel anatomy. Morton's Neuroma is an enlarged nerve that usually occurs between the third and forth toes. The reason the nerve enlarges has not been determined. It can be caused by flat feet, which could cause the nerve to be pulled toward the middle, leading to irritation and possible enlargement of the nerve. Alternatively the wearing of high heels can cause more weight to be transfered to the front of the foot and tight toe boxes can create lateral compression. As a result, there is more force being applied in the area of the nerve compartment which becomes compressed. It is more common in women than in men. An MRI scan can be used to ensure that the compression is not caused by a tumour in the foot as well as determine the size of the neuroma, and whether the condition needs to be treated conservateivly or aggressively. An X-Ray can also be taken to rule out possible fracture and examine the joints and bone density, ruling out possible rheumatoid arthritis. Tarsal Tunnel Syndrome is an extrinisic or intrinsic compression neuropathy of the posterior tibial nerve or one of its branches. Patients who have presented with the syndrome have related a history of previous ankle sprains, ankle fractures and flat foot. Symptoms include otherwise unexplained weakness in the intrinsic foot muscles (deep within the foot) as well as a decreased plantar sensation and swelling in the tarsal tunnel region. Morton's Neuroma is documented as a differential diagnosis of tarsal tunnel syndrome. We are unfotunately unable to give you a direct referral with regards to recommending podiatrists and other specialists. All the best!
