and yes I will certainly buy one and give it a go anything to reduce the swelling, many thanks for the suggestion
, swelling and pulled muscle inside thigh really sore
make walking difficult and nausea
, I know returning back to work is putting extra pressure on leg
, but I cannot feel frustrated has not feeling any progress at all even a small sign would be good and helpful , but nothing be glad when I see my surgeon in October has waiting for the other knee to be done, in one way be glad to have it done soon so give the Op knee plenty of rest too, also cannot help to compare oneself to others especially when they getting on so well,
, its so difficult to walk any long distant or for very long and still using crutches sound like I'm the only one at this stage in this situation, will not go to DR has they really don't take it seriously so wait to see surgeon 
, unfortunately knee not doing to good seems like build up pocket of fluid under knee and
severe red and pain/ soreness in inner thigh near knee , very painful to walk though got an appointment to see doctor tomorrow to see whats going on so not doing to well, trouble is we all suffer different swellings/ pain so hard to know what is abnormal or not,
