Have you ever experienced the boomerang effect?  

For the last two and half weeks I've been sick with yet another cold, and just when I thought it was getting better and the symptom's were going away here comes another soar throat.

I thought oh NO not agin! and I begun another regiment of over the counter medicines I then thought why did that happen? anyway fast forward another three days later, and I'm starting to finally feel better I'll just have to hope that I do not experience any return cold symptoms.

Have you ever experienced the boomerang effect where a cold came right back and knocked you back in bed? and why do you think this happens? I have my own theory's but I'd love to read yours.

By the way I still have this annoying cough that will probably take weeks to finally go away aww men haha sniff COUGH! sorry I didnt mean to cough all over the forum COUGH COUGH!
