(Excerpt from The Endless Journey Home by Specialist Joe Collins)
Hypersensitivity and anxiety usually go hand-in-hand. The most common symptoms are sensitivity to bright light, loud noises, large crowds, unfamiliar places and/or being easily startled.
At first these symptoms may appear to be slight or almost unnoticeable, but a soldier will be able to begin to feel an increase in an anxiety levels and discomfort when exposed to some of these elements.
Over time, and without treatment, symptoms can get worse. In several cases, those who suffer from PTSD and have not sought proper help can suffer severe anxiety attacks (panic attacks) and often complain of migraine headaches if they are triggered by one of these symptoms.
