Definitely a good thing to get tested for. It is pretty common in my area, BOTH of my parents have it and so does my brother who is only 17. Also, both of my neighbors have it and their three sons. One of them was bedridden for about a month when it was at its worst. He is the reason everyone else in my family got tested.. They were told no by a couple doctors until they went to a specialist and he tested them the expensive way and now everyone is feeling 100%.
Funny thing is, everyone had completely different symptoms.. I should get tested at some point...
