Hi Corgidog, and welcome!

It looks to me as if Herco hasn't been here in a while and so may not reply but you never know.

I'm no authority on the drugs you mention but noticed on Drugs.com that burning is mentioned as a rare side effect of escitalopram:

Escitalopram Side Effects: Common, Severe, Long Term - Drugs.com

But most drug listings involve a whole boatload of possible side effects. One good way to find out if symptoms you're having are caused by a drug you're taking is to do exactly what you're doing--stop taking the drug for long enough to see if the symptom goes away.

If that doesn't solve the problem, you might want to think about something you're doing that might be bringing on the burning. Have you changed shoes? Shoe-fit problems can cause an astonishing number of problems.

Or maybe you're sitting, standing, or walking in a certain way that you could modify? If you're in a wheelchair most of the time, just adjusting the legrests can solve quite a few issues.

All this may sound ridiculously simple-minded but I have diabetes and MS and have discovered that looking at the simple, "obvious" possible causes of a problem is a very good idea.
