When one suffers from back pain, knee pain and other pains that occur as one grows old, the way I do, one must move forward, as if the pain does not exist in order to have an active public life. A young, female person, such as yourself, may suffer from certain pains, especially at critical times of the month, that are hard to ignore. Sometime medications may be used to help with this pain. Sometimes "folk" remedies may work for you. Naturopathic doctors and DCs have their own approaches for dealing with pain that can be very effective. By the way, all pain is "in the sense that only the person suffering from the pain can feel it, or experience it." Pain is "subjective." It cannot be seen, directly by observers, outside of the patient, herself or himself.
Very good question.
