hi,
thank you for your query.
pain and warm feeling at the
dialysis site can be due to-
thrombhophlebitis,venous stenosis,
thrombosis, infection, pseudo-
aneurysm.
i would definitely advise you to consult your doctor but you can wait until morning.
till that time you can apply heparin ointment over the affected area.
thank you,
wishing you good health
