Thanks for your query
and tingling sensation
all over the body is not related to pulmonary embolism
nor with warfarin
therapy. You have to search for other pathologies to find out the cause.
I think following pannel of tests will be of help to you -
1. fasting and post-prandial blood sugar
3. thyroid profile
4. Nerve conduction velocity testing of all limbs
5. Lipid profile
6. A repeat chest x-ray
Consult a pulomonologist to get examined.
