i am extremly concerned about my mom. She started having tingling and numb feelings in her feet that started crawling up her legs and causing a heaviness in her feet and legs and sometimes continues up towards her back. She gets nauseous and feels like she is going to pass out. This has been going on for over a year now and is continuing to get worse. No one seems to know the cause. She s been to two neurologists and they haven t been able to pin point the cause. I ve watched my mom s health go down over the past year and I don t know how else to help her. She s had an MRI and a CAT Scan and they haven t found any cause for the symptoms. My mom is someone that never complains and has a very high pain tolerence, but she says she can t go on feeling this way. I just don t know what else to do or where else to go to get her help... She says when she stands up she has to wait a minute or two before her brain tells her feet to move, but it eventually connects. She said that the numbness and heaviness starts in her feet and begins climbing up her legs and into her back. She gets nauseated and starts to feel as though she is going to pass out. I am getting so concerned about her but I don t know who else to take her to get help....i welcome any suggestions at all.
