Sorry, this isn't a health related post, but just wanted to put an idea out there. I was thinking about this forum, and because I work in marketing, I often have to research patterns and behaviours of customers/clients.
Not sure if anyone else has noticed, but HA worries almost seem contagious. I've been on this forum for nearly a year now, and noticed a few trends. Back in December - Jan, we had quite a few people posting about MS/ALS related worries. February - April, I could see a trend with bowel worries and more recently there seems to be quite a few posters (myself included) with lymph node worries!
I don't know if anyone else has noticed patterns, but maybe health anxiety can be contagious. Obviously there are lots of triggers on here, which may explain it all.
