By cobanding I assume you mean the 3m coban wrapping system Yesfir decongestion phase -intensive wrapping every day by a therapist or in rehab such as at Mount Wilga . I am too impatient for that. I would rather wrap myself ,might be good if your spending that long on transport or there are lots of other wraps such as velco ones that are easy on and off to give a bit of extra pressure in addition to a compression garment.Just depends on what works for your situation.I likewise find forearm and back of hand are trouble areas.I have found when my neck and shoulder are stiff and tense then it blocks up lower down in my arm.So I work harder on that area with stretches.I also find a soft roller massage ball eg Kmart.Tennis ball sized,soft rounded knobs.Rolled elbow armpit helps unblock and allow lymph to flow.also on forearm and everywhere.in upward direction towards armpit helps soften and move fluid.i have found small pieces of mobiderm blocks (7 foam wrapped cubes cut off a roll,looks like chocolate bar shape,google mobiderm) under my compression sleeve definately help when areas are getting firm.i also have a full mobiderm adjustfit sleeve for use sometimes if it getting a bit firm.I recently also got a jobst farrowrap sleeve to go into of my compression when I go for walk and hand piece.the handpiece is great and I been using that more.easy to put on.Gives a bit of extra pressure for the back of my hand and helps push fluid out.I can wear it when driving and doing some jobs .whereas if I wrapped it in comprilan bandages hand becomes less flexible while wrapped so hard to do tasks like typing .Just depends on degree of flexibility you can stand,what you need.So many options.Talk to your therapist.The main thing is dealing with it and managing it.The more you can keep the swelling down the better.It will slow the progress of the disease.If you don't it will get harder/firmer and eventually the fluid gets stuck(protein particles get too big to move through membranes).So it great your feeling like your ready to look for some new ideas and work on maintaining it better.Like they say always learn,add things to your toolbox of ideas so when it flares up you have options to deal with it
