I like to think I have a fairly strong immune system, though I don't. I'm an asthmatic (though I've been fortunate enough never to have a severe asthma attack) which means I often feel sub-par when I encounter a trigger, which tend to be everywhere. I see an immunologist to keep myself from feeling sick often. More infrequently yet, I suffer from migraine spells, which have been so bad since I've been young that it has landed me in the hospital in more than one occasion. Unfortunately, we haven't been able to learn what triggers my migraine attacks. It really all depends on what is causing me to be sick to determine what I'll do.
If I have a migraine, I really cannot do much of anything. They come on almost suddenly and can follow for hours with intense, throbbing pain. I become lightheaded and beg anyone who is willing to get me a hot compress to put over my eyes and reduce the volume in the room. A migraine just makes you want to hide in a quiet, dark cave. With my asthma, I just have to keep an inhaler on hand, else I can become dizzy. The best thing for my allergies is to remove myself from the triggers, such as pollen or latex, but if it is too bad I might have to use my epi-pen. In general, being sick I want to crawl into bed and be left alone.
