Okay, welcome to the forum and your neuro knows very little about MS!
There is rarely a good correlation between where the lesions are in MS and the symptoms we suffer. Every once in a while we can point to a lesion and say," Aha! There is the culprit!" But this is not very common.
Sesides, many of the symptoms you report would be cause by lesions in your spinal cord. Where were the two lesions they saw? Have you had your spinal cord imaged?
You have now had two separate attacks. If you have any objective evidence of damage to the nervous system on physical exam or on testing, and the blood work up is negative, you have enough evidence to diagnose MS, ESPECIALLY with 2 lesions in your brain.
You have drop foot. Do you have any other abnormalities?
Your neuro is a idiot if she thinks that stress can cause drop foot! You need a new neuro, preferably with a doctor that knows something about this disease. She is not doing you any favors.
Here are an article you might read to get a better idea of what I am talking about:

and here is a discussion of the many myths that neurologists seem to hold about MS.

Once you read these you'll know why we get so upset when someone tries to match lesions to symptoms.
We are here to help you through this. All Neurologists are not created equal and you have a real dodo if she is suggesting that, because she is not educated enough that YOU must be all stressed out. Sheesh!
