A device for applying compression to a thigh of a patient, the device comprising: a garment configured to be positioned on the patient's thigh, the garment comprising: a proximal edge, a distal edge, an internal garment passage configured to receive the patient's thigh; and at least one inflatable chamber; and a control unit configured to supply pressurized fluid to the at least one inflatable chamber using the following inflation/deflation process: inflating the at least one chamber from an initial pressure to a first pressure; maintaining the at least one chamber at the first pressure for a first predetermined amount of time; changing the pressure in the at least one chamber from the first pressure to a second pressure, wherein the second pressure is greater than the initial pressure; maintaining the at least one chamber at the second pressure for a second predetermined amount of time; changing the pressure in the at least one chamber from the second pressure to the first pressure or a third pressure greater than the second pressure; maintaining the at least one chamber at the first pressure or third pressure for a third predetermined amount of time; and deflating the at least one chamber to zero pressure or a fourth pressure, the at least one chamber consist of three separate inflatable chambers (32, 30, 28) where the pressurized fluid is supplied into the first inflatable chamber through an inlet tube, into the second inflatable chamber from the first inflatable chamber via a transfer tube, into the third inflatable chamber from the second inflatable chamber via another transfer tube, characterised in that, the inflatable chambers (32, 30, 28) are arranged between the proximal edge and the distal edge and with the third inflatable chamber comprising an upper edge that is arranged and extends along the proximal edge, whereby the upper edge and the proximal edge are defined with a concave recess. a proximal edge, a distal edge, an internal garment passage configured to receive the patient's thigh;
