Can anyone help with my persistent back pain at 15?

Let me suggest that you never move any weight on your ankle until it is completely healed. Even slow walking puts too much pressure on the fracture, and it can still cause more injury.Please follow your doctor's advice

Its not like that. Any selective Cox2 inhibitor will do the job.

Acupuncture points help in rehabilitation of anterior cruciate ligament (ACL) . Using the local and distal points in acupuncture, it helps in repair of ligaments and reduces the rehabilitation time.
Acupuncture combined with seed and magnet therapy, moxibustion have miraculously helped in treating ACL tear naturally I.e without surgery.
One can lead a normal life once a patient is pain free.
The treatment time depends on the severity of the patient but nonetheless 12- 15 sessions will be required which will help reduce the pain and repair the ligament. Further course of treatment can be advised post the knee scan.

For your knee pain, please visit an orthopedist. He will evaluate your condition to know the exact cause of knee pain. It can be caused due to sprains, arthritis etc. Based on the diagnosis and cause, a proper treatment will be suggested to you which can include physiotherapy, medications or surgery. 

You may have a broken toe. Dropping something heavy on the toe or stubbing it hard can cause a broken toe. Symptoms of a sprained toe include pain, bruising, and difficulty moving the toe. To be sure, you should get an X-ray at a clinic or hospital. Icing, resting, and keeping the toe safe from injury will give relief to the pain.
