Symptoms
Symptoms of MCS may be mild to disabling. Symptoms may be physical or psychological in nature and are essentially those that are disruptive to the individuals’ mental or physical wellness and that the individual attributes to exposure to a chemical or scent.
By far, the most common symptoms are vague, non-specific complaints: feeling tired, "brain fog" (short-term memory problems, difficulty concentrating) and muscle pain. These complaints are common to a large number of medical conditions, from psychiatric conditions, such as major depressive disorder, to neurological conditions, such as orthostatic intolerance, to high blood pressure, autoimmune diseases and cancer.
A partial list of other symptoms patients have attributed to MCS include difficulty breathing, pains in the throat, chest, or abdominal region, asthma, skin irritation, contact dermatitis, and hives or other forms of skin rash, headaches, neurological symptoms (nerve pain, pins and needles feelings, weakness, trembling, restless leg syndrome, etc.), tendonitis, seizures, visual disturbances (blurring, halo effect, inability to focus), extreme anxiety, panic and/or anger, sleep disturbance, suppression of immune system, digestive difficulties, nausea, indigestion/heartburn, vomiting, diarrhea, joint pains, vertigo/dizziness, abnormally acute sense of smell (hyperosmia), sensitivity to natural plant fragrance or natural pine terpenes, insomnia, dry mouth, dry eyes, and an overactive bladder.

Famous quotes containing the word symptoms:
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
“Social movements are at once the symptoms and the instruments of progress. Ignore them and statesmanship is irrelevant; fail to use them and it is weak.”
—Walter Lippmann (1889–1974)
“The human condition is such that pain and effort are not just symptoms which can be removed without changing life itself; they are the modes in which life itself, together with the necessity to which it is bound, makes itself felt. For mortals, the “easy life of the gods” would be a lifeless life.”
—Hannah Arendt (1906–1975)
