Lacustrine systems include all wetland and deepwater habitats associated with depressions or damned channels greater than 8 ha in area, and which have less than 30% of their area dominated by trees, shrubs, or emergent vegetation.
There are a wide variety of conditions that can cause thigh pain. For example, thigh pain can be caused by physical activity, injury, or age-related wear and tear on the hips and knees, which may cause pain or discomfort in the thigh area near the joint.
Other possible causes of thigh numbness include problems with nerves that connect to the lateral femoral cutaneous nerve. For example, nerves in the lower back connect to the nerves of the thigh, so disc disease that compresses nerves in the lower back may cause numbness in the thigh. It's likely that your doctor can find out the cause of your numbness just by reviewing your symptoms and performing a physical examination.
