In many places around the world (and even in rural America), treatment options are very limited. There may only be a remote clinic staffed by a nurse or physician's assistant. Urgent health care may not be available.
No care and self-care are the main options when professional health care isn't available for whatever reason. Self-care may include self-massage, over-the-counter pain relievers, hot or cold compresses.
Some patients begin with a program of simple range of motion exercises. Rhythmical and repetitive activities such as walking with reciprocal leg and arm action can be very helpful for some people. Basic yoga classes are often offered on public television or available from the public library on tape or DVD for home viewing.
If you feel you need the services of a medical doctor, chiropractor, or physical therapist, you may be able to arrange for a long-term plan of billing for services. Many local health care professionals are willing to spread payments out as far as needed by the patients/clients. It's always worth asking. You have nothing to lose and everything to gain.
