[|Human|] Hi, this morning ( 7am) I collapsed onto the bed while getting dressed......just seemed to pass out briefly. The day passed pretty normal. About 20 minutes ago (9.15) I had just gone to bed , lying on my back.....the whole room started to spin and I became quite clammy....pins & needles and numbness in right foot. I don t feel right and feel if I do much I will fall over. I am a 66yr male, 6 ft and 83 kg, reasonably fit and well. Should I be concerned right now? thanks Max Gawler
[|AI|]  Hello! Numbness in half body or a limb can be caused by a vascular brain disease. If it lasted for less than an hour it can be a transient ischemic attack, but it lasts longer it can be a stroke. Anyway you have to see a neurologist to see objectively for any neurologic sign, and you have to some examination such as Doppler sonography of cervical arteries, CT scan and also a cardiac check-up to rule out or find out a heart condition or high blood pressure. I hope to have been of help.
