A heat sensation or sudden feeling of warmth can be a sign of blood clot or deep vein thrombosis. It can also be due to pinched nerve or due to diabetic neuropathy. What I would like to add is that the nerve compression may be superficial too (lateral femoral cutaneous nerve), that comes from the hip area and gets pinched. This condition is called meralgia paresthetica and is often due to weight gain or wearing tight clothes and belts. Losing some weight or wearing loose clothes and belts often helps relieve the pain/numbness/tingling. Also injection of lignocaine (anesthetic agent) at the site helps. In your husband’s case you can apply a pain reliever at the site and see if it helps. Please consult his doctor immediately and get this investigated. Take care!
