My mom was just in the hospital on Friday, the dr. think she had a mild stroke due to the pains in her left leg but when they released her Friday night. They could NOT find no sign on a stroke all of the test came back no signs. Now, she is still complaining about the pain in her left leg. Now the Dr' wants her to have a DPS done at the hospital tomorrow. Will this test reveal if there is a blockage in her leg. You can see little veins and bumps and the leg is real hard. What other kind of test can they do to help clear the problem up. My Mom is 76 years old and is in very good health, but she has been complaining about the swelling in her legs for now about 2-3 months, but no dr has been able to see what the problem is. She had a complete workup while she was in the hospital of Friday, but they were looking for signs of a stroke and nothing else. What else can be done?
