Why do I experience weakness and swelling in my body?

You have patellofemoral pain syndrome. This condition causes pain around or under the knee cap, which can spread to the side of the knee. It's often due to overuse, weak muscles, or improper knee-cap positioning. Exercises to strengthen leg muscles and supportive sports shoes can help. A key part of treatment is avoiding activities that worsen the pain. 

You could have what’s referred to as a bunion. A bunion is a bony bump that forms on the base of the big toe. Tight shoes or heredity can be the cause of it. If it’s getting swollen and larger, it’s advisable to wear comfortable shoes and apply ice to reduce swelling. In some cases, surgery may be necessary if it’s very painful.

Causes of the lower back pain at right side that occurs after one sits for more than thirty minutes include a number of factors which can range from poor posture or muscle strain to herniated discs. However, it is best to visit an orthopedic specialist

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.
