The symptoms vary enormously between people with myasthenia gravis: 1  The muscles around the eyes are most commonly affected first, as these are constantly used and can quickly tire. 2  Muscles around the face and throat are also often affected. 3  Weakness in the arms, hands, fingers, legs and neck may develop.
In its most general form, a nipple is a structure from which a fluid emanates. More specifically, it is the projection on the breasts or udder of a mammal by which, in females, breast milk is delivered to a mother's young.
The cause of nipple pain and breast tenderness during pregnancy can be blamed on the excess of the hormones estrogen and progesterone that are coursing through a womanâs body at this sensitive time. There is also more fat (the good kind) that is building up in the breast, and there is an increased blood flow to the area as well.
