I feel numbness in my legs, legs are cold or hot, numbness in my left cheek, can hardly move fingers?

Hello, 40 years male having recurrent (happening a few times during the day – and night as well); episode will last for just one minute – no longer than that – during this time I feel very weak in my left side – lower lip drops – can’t talk – speech is slurred – feel numbness in my legs and have various sensations all over my body – including feeling legs are cold or hot – feeling numbness in my left cheek – left side of body very weak – can hardly move fingers – however I can walk un-aided and raise my arms & hold things; after one minute back to myself – though numbness does not go away.
