Medical Supply Superstore has a wide selection of Compression Therapy Products that vary in strengths from 8-15 all the way to 30-40. We have knee high stockings to pantyhose in lengths. Circ-aid and lymphedema sleeves are also available. Prescriptions are only necessary if you are getting 30-40 compression strength or if you want taxes on the purchase taken off. Note: Patients with Duke Select may be eligible for coverage with a prescription. Come see the largest selection in the Triangle area.
