Is dialysis uncomfortable?
You may have some discomfort when the needles are put into your fistula or graft, but most patients have no other problems. The dialysis treatment itself is painless. However, some patients may have a drop in their blood pressure. If this happens, you may feel sick to your stomach, vomit, have a headache or cramps. With frequent treatments, those problems usually go away.

Low blood pressure (hypotension).
