You started the same thread with the same title in the same forum 2 days ago -
here it is. If you have further questions, ask in your original thread! Having said that I have this one open now so I'll answer you here haha..
Microns are really cheap on the internet. There is some controversy about what exactly causes cotton fever but the symptoms fit with a shower of bacteria entering your blood stream, then your body fighting them off. It could be a particular bacteria that grows on cotton, but you'd get the same symptoms with any bacterial shower that your body is able to take care of so some cases could be from other contaminants. If your body can't take care of it, that's when you get septicaemia/blood poisoning. In addition, bacteria can lodge on your heart valves and erode them over time (infective endocarditis).
Cottons are better than no filter at all, yes, but microns are
so much better. Especially for pills to remove fillers/binders, but also to help keep things sterile and remove insoluble cutting agents from street drugs that you really wouldn't want to end up in your veins.. It's up to you, it's your health..
If you get cotton fever, drink plenty of fluids, get some rest, some people say a hot bath helps the symptoms. If they are worsening or not easing up at alll after a few hours, or you are at all concerned, get some medical help in case you are developing septicaemia as the initial symptoms can be the same..
