I've been noticing this strange warm sensation in my lower leg lately. It pops up for about a minute then just disappears on its own. There's no pain or swelling, just feels like heat is leaving that area. Occasionally, I'll feel it in my back or shoulder too, but it's pretty rare. Could this be linked to having had Covid a couple of months ago? I had my d-dimer checked back then and it was normal. What might be going on with these sensations?

The intermittent, brief, and painless warm sensations in your lower leg, back, or shoulder could be due to various benign causes, such as vasospasm (temporary blood vessel constriction), nerve sensitivity, or muscle relaxation, and while it's reassuring that your D-dimer levels were normal after COVID-19, it's still possible that you may be experiencing post-COVID-19 symptoms, such as autonomic nervous system dysfunction or peripheral neuropathy, so consulting a doctor to rule out any underlying conditions and determine the best course of action is recommended.
