Thanks for using Healthcaremagic,
After going through the detail provided by you, your tingling sensation
may be some kind of neuropathy.
It is commonly due to cervical spine problems causing pressure on nerve root, but it needs to be confirmed by clinical examination and medical tests like nerve conduction study
and pressure may be detected by M.R.I of cervical spine.
Treatment depends on cause.
Other differential are nutritional deficiency
, alcoholic neuropathy
Your medical check up is already done and everything is normal so do not worry only,for high cholesterol
take care of diet and if stain is prescribed to you take it regularly.
Hope this helps.
