This is Dr. David
I am sorry for the delay
and your rash and swelling symptoms.
rash can be from viral infection or from statis of blood in the legs from swelling and edema and poor circulation.
I am worried about your ankles swelling up from poor circulation or liver or kidney problems
eating too much salt can cause swelling in the ankles
new heart weakness can cause swelling in the ankles as well
can you upload a clear jpg photo of the rash changes in your legs and arms so I can better help you?
do you see the "add file" link where you can upload a clear jpg photo?
