Bodily inner vibration & land slipping feeling

My wife cought cold during Navratri and she also had tonsilities problem too. So we went to Doctor, as usual the treatment was given like Azid 250, Rhino, Sompraz like medicines to control the cold and tonsils pain. After two or three days it has again started the same way with vertigo like feeling and headache. Again we went to Doctor at that time my wife's BP was very low, so advised to have sweet things to eat. But it is of no use. The vertigo converted in feeling like land is slipping below her feet and body felt vibrations inside. Though it was not physical vibration she was as normal as other. But she felt these sort of sensation. We went to Specialist General Physician he prescribed some cold medicine. He has given medicine like Stugeron, Vertin, Neurokind etc. But of no use. We have done some blood tests only HB was 10 other wise everthing was normal. Finally he advised to consult ENT Doctor. We went to ENT doctor and did Audiography and ENG test for balance but it was also OK. ENT Doctor referred to Neuro Physician and had MRI done of Brain(L) was normal, Neuro advised to go to Psychiatrist. Though it was not at all psychiatric problem. Again I contacted a Homoeopath and advised me to have Vitamin B-12 test and X-Ray PNS. Vitamin was normal but Sinus was found hazzy. So I am now taking Homoepathy treatment. Here cold is under control but the sensation of Land slipping from her feet is still there and she is having inner vibrations which we cannot feel by touching here bodily.

Kindly suggest me if anybody had such problem and got recovered. Suggest any Doctors near Ahmedabad or Mumbai.
