Deep Brain Stimulation and Parkinson ’ s cause dyskinesia or other side effects . If this happens , your programmer will simply turn down the settings .
+ Infection The risk of infection is low , but it can happen , especially with repeated battery changes over time . Your doctors limit risk with careful protocols in the operating room . You can limit risk by keeping your incision clean and dry . If the skin becomes red , painful , swollen or warm ; the incision oozes ; or you have a fever , contact your doctor immediately . Infection is typically treated with intravenous ( IV ) antibiotics and rarely with removal of the battery .
+ Bleeding Bleeding around the battery is possible , particularly if you have bleeding problems or take blood thinners . ( Usually these medications are held temporarily ahead of battery replacement .) If you notice swelling or significant bruising or bleeding from the incision , contact your doctor right away . Most of the time , bleeding slows with pressure bandages or other treatment . If not , you may need additional care .
After battery replacement , pay close attention to how you feel . Pain is common and expected . But if you have new weakness or numbness , or changes in talking or walking , you should seek medical attention right away . If you have considerable worsening of Parkinson ’ s symptoms , talk with your DBS doctors immediately . Symptoms can increase with any surgery , pain medication or other stressors . But they should improve in a few days to weeks . If not , ask whether you might have a complication and how you and your doctor can look for and fix it . Remember , you know yourself or your loved one best and you are your best advocate .
