As an analogy only, the brain is essentially a radio. Tweaking your consciousness can let you tune in to all sorts of things that you usually tune out.
This is a controversial area, and there is a lot of pseudoscience and woo woo stuff tossed around. However, there is a small body of work which demonstrates some metabolic effects of EMFs at usual densities for cellular or wireless networks:

http://www.ncbi.nlm.nih.gov/pubmed/25084839
http://www.ncbi.nlm.nih.gov/pubmed/24772943
http://www.ncbi.nlm.nih.gov/pubmed/22047460
There are plenty of other papers out there, too. Some have not found these correlations, but given the number of independent researchers who have observed various biological effects of EMFs, I think it's reasonable to assume that they "might do something", and that something might or might not interact with your neurology in an odd way.
Of course, the explosion of wireless nets over the past decades also coincides with the widespread distribution of various pollutants and toxins - so even if you can find differences in the population from now and then, proving any kind of causative effect from pure EMFs seems difficult or impossible.
Personally, I do believe that when I am most anxious, my CNS picks up on all kinds of things that are not otherwise significant, because anxiety seems to crank up the signal gain on all my perceptual processing. It would not shock me to learn that some kinds of radiowaves is in the list of "all kinds of things", but I don't know how actionable that is.

I don't think this has been proven by any stretch of the imagination. The best that we have are some conflicting reports and the observation of very specific changes in very specific circumstances. There is no smoking gun, and there is certainly no reason to think that radiowaves cause "nerve damage". If that were the case it would be pretty easy to observe, because it's pretty easy to objectively measure nerve signaling.
Here is a single, very low impact study which finds a correlation between nerve signaling and EMFs in rats:

Here's a contrary study which found *neuroprotective* effects from EMFs, also in rats:
