<s>[INST] my husband has been having tingling/numbness in his hands and feet .... and his arms....almost as if he has slept on them and you get that tingly feeling. he hasn t really felt right since June....very light headed....has had to pull over when driving... the right side of his face has now started getting prickly now. 2 weeks ago he went to the doctor and she thought the tingling/numbness and the light headedness/dizziness are not related. she ordered blood work but they called and said it all was normal. she ordered a neck xray (thinking maybe a pinched nerve)...we haven t gotten the results of that yet. the past 2 days he has felt worse.....nausiated and hot flashes... last night, he woke at 4am and said his heart was racing and he just didn t feel right - his left arm was tingly again. [/INST] Hello, In my opinion, neurological conditions such as Chiara malformation, peripheral neuropathy, etc. should be considered as possible conditions that may cause such symptoms. The first step in achieving a correct diagnosis is a careful neurological examination. Tests such brain and neck MRI, nerve conduction study, are also necessary. Discuss with your husbands Neurologist for these issues. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  </s>
