I help to run a registered charity for people suffering from the illness M.E. (Myalgic Encephalomyelitis), in England, UK.  
Electromagnetic sensitivity including wifi is not uncommon as a co-morbidity with ME/CFS. Multiple Chemical Sensitivity appears to be more common as a co-morbidity with ME/CFS sufferers.

I know personally of two M.E. sufferers who cannot use mobile phones and react badly to other electrical products, e.g. televisions.

I myself cannot use a mobile phone unless I use shielding for my head, otherwise the pain I experience is like being hit on the head with a hammer.

I know of a lady who does not have M.E., but she is extremely electrically sensitive, especially to mobile phone masts. At times she is so ill that she has to live in a shielded hut in a garden.
