Respected user, hi I evaluated your query thoroughly.
*Relates to Neurovascular involvement following postural habituations.
*
Ultrasound is normal is appreciable but it`s not telling reason of your
discomfort & suffering.
*You require detailed Neurophysiological evaluation by Neurophysician to
arrive at the diagnosis and management of it perfectly.
*Till that time my suggestions are :
@ Avoid sitting / standing in same posture for prolong period of times till
possible.
@ Try to give body proper relaxation phases along with all hactic schedules.
@ Some amount of light exercises daily at home without failure.
@ Avoid
smoking / alcohol / abuse substances if any.
@ Avoid tight socks, shoes.
@ Keep BP , Blood sugar,
Cholesterol levels under control.
Hope this clears your query.
Thanks for using Health Care Magic & reviewing my answer.
Regards.
Bye dear take care.
