<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had a pace maker put in in 2011 next day by left arm started swelling. I now have lymphedema on my left side, face, arm, the hole left waste up. The pace maker is no longer in. But with this lamp fluid is in my inter ear I get dizzy, if I turn my head I get dizzy, a lot of times when I walk my head feels like I am going to pass out and my legs get weak. And when I get to my chair and set down I feel like the blood is flowing out of my body, from head to toe. Chip  <response>: Hi, Regarding your concern, I would explain that your symptoms could be related to orthostatic intolerance. For this reason, I would recommend performing a head up tilt test to investigate for this disorder. I would also recommend performing some other tests: -a Doppler ultrasound of the carotid arteries-complete blood count for anemia-blood electrolytes for possible electrolyte imbalances- a cervical spine X-ray study for chronic degeneration. You should discuss with your doctor on the above tests. Hope I have answered your query. Let me know if I can assist you further.
