Hi Allison,

As difficult as it may sound , keeping it moving will help to decrease the swelling by encouraging the blood flow.
If I am brave my physio will do some deep tissue massage----yes, it is very painful but it can reduce the swelling.
Also the use of some type of tubigrip applied before you put your leg to the floor will help also.
This is something that often requires desensitisation to enable you to put it on but there are some less constrictive ones that will give light support and you may be able to work your way up to a tighter one.
I take diuretics but not for my RSD--they make very little or no difference to my neurogenic oedema.

Good luck with it
Tayla
