Welcome to HealthcareMagic forum.
Abnormal position during sleep can cause compression of neurovascular structures resulting in tingling
, discomfort and pain. The symptoms can last for few minutes to days depending on the amount of nerve damage
. These phenomena can explain the symptoms you had in the upper limbs, while I am unable to explain the lower limb weakness too.
If a definite weakness is documented by your doctor, then you would need to get a CT / MRI scan of the brain and rule out intracranial pathology such as ischemia
A specific treatment can be planned based on the results of scan. If no significant / clinically co-relating pathology is found, then we may attribute these symptoms to anxiety
Hence a scan is mandatory. Discuss with your treating doctor.
Hope this information suffices.
