Hi Becky
Sorry to hear that your dad is having problems, hope he gets sorted quickly and makes a full recovery.
The nurses on the Helpline are probably best placed to advise but I think the answer to your question is yes. In our local myeloma support group there a small number ( all men ) who have had similar problems.
I have just started treatment myself and have daily blood thinning injections of enoxaparin to prevent clots. So one assumes that this is something which the medics will have on their radar screen.
I honestly don’t know what the answer is but I try and do as much exercise as I feel I can cope with to keep the circulation moving.
Hope this helps
David
