I am not aware of an infection which would only produce diffuse muscle twitching without any other symptoms. The muscle twitches may be secondary to benign fasciculation syndrome or possibly a electrolyte imbalance. Stress and excessive excercise can also cause muscle twitching. You should discuss this with your doctor, and if there are any concerns then see a neurologist. Good luck.
Did you get headaches, sore throat (but without fever), start coughing a lot ... things like that?
On the other hand, there is such a thing as second hand solvent exposure: solvents can be expelled from one's breath. i.e. the 'gulf war syndrome' vets and many people in our general population, too. Usually it is from getting vapors of the ethylene glycol monobutyl ether chemicals in one's eyes; but breath to breath & as you suggest, as well(?) Do you recall your eyes burning and hurting, then flu-like symptoms and feeling oh so tired?
Fatigue from exposure to this chemical shows up differently, and a couple of small add on blood tests will show it up. Although unless you have other odd symptoms such as with CFS (aching joints, short term, memory loss, depression, 'fly off the handle over nothing' personality changes ... etc; endocrine disruption) don't worry about it. It wouldn't be this chemical family.
Ask your doctor to order a Reticulocyte Count and ask for comment on the size and shape of the red blood cells. ... AND the Complete Blood Counts with differential (the combined tests are around $70 in our area) The headaches and neurological effects of this chemical SCREAM LOUDER but the provable harm is the fatigue caused by prematurely destroyed red blood cells.
