I suggest you consult with an orthopedic specialist right away. This injured ankle may have damaged the joint, which led to a throbbing pain. During this time, you may relieve the pain by applying ice to the affected area; taking antinflammatory medicine and keeping your leg elevated. But these are only short-term fixes, which would require an official diagnosis and treatment from a specialist.

You could be having turf toe, which is typical when doing sports such as football. Turf toe occurs when the big toe joint is injured, and can cause pain. Symptoms are swelling, pain, and limited movement of the toe. To assist in the healing process, try to rest your foot, use ice packs, and wear supportive shoes. Ignoring the pain, and consulting with the family doctor is a better option.

Given your age and history of osteoarthritis, it is most likely caused by the wear and tear on your joints. Losing some weight gradually with a healthy diet could relieve the pressure on the knees. Additionally, physical therapy may enhance flexibility while building up muscles around these areas. 

You might have muscle pain coupled with pressure on the neck and the shoulder region. Muscles are likely to be tensed or strained bringing about such signs. The issue of muscle dropping below your clavicle and squeezing your neck could result from sitting or standing with drooping shoulders. You can ease them by keeping the right body posture always, engaging in mild stretches that won’t hurt much, and using warm towels on those affected spots. 

Osteoarthritis is a condition that can cause pain and stiffness in your joints. The tissues that cushion your joints wear away, leading to this problem. Sometimes it may be due to old age, an injury, or obesity. You can do low-impact exercises such as walking or swimming to relieve the pain. Alternatively, apply ice packs or use heating pads on the affected area. Furthermore, purchasing footwear with proper arch support may also alleviate discomfort.
