Why Is My Fever Persisting And Leg Swelling?

If one leg/thigh/hip is bigger than the other, it might be because of a muscle imbalance. This means that one side is stronger than the other. You may develop this condition by constantly using your one leg when walking or doing physical exercises. To solve this problem, ensure workouts that will serve each side equally.

I think you got a scratch on your knee when you fell. It's okay to have pain, redness, and swelling around your wound. This is because the fall has injured your skin. The solution is to gently clean the wound using soap and water, apply an antibiotic ointment, and cover it with an adhesive bandage. Always change the dressing daily until it heals. Opening up is necessary if the pain worsens or you notice any infections with symptoms like pus, light redness, or warmth. 

It’s common to experience back pain in your age group because of several factors. It may be due to rapid growth or carrying a heavy backpack. Some indications for this condition may include tenderness, rigidity, or uneasiness. To solve this problem, don’t carry heavy bags and do exercises that will tighten your muscles. Also, be mindful of how you sit or stand. If the discomfort persists then it would be wise to inform an adult about it.

Perhaps your backache is associated with nerve injury. I recommend that you see a neurologist for an accurate diagnosis and treatment. They will perform further tests and establish what is causing your pain.

Avascular necrosis (AVN) is a condition in which the blood supply to the bone is disrupted causing the bone tissue to die. Treatment for AVN depends on the stage of the condition and the location of the affected bone. Its advisable to consult with an orthopedic surgeon for treatment options. The doctor may recommend physical therapy, medication, or surgery depending on the severity of the condition.

You need to rest and avoid excessive strain. You may take pain killers, try heat or cold therapy. Do gentle stretching exercises and maintain good posture. 

Seems to be like you may have vertigo and a little bit of tightness in your back. Vertigo can make you feel like you’re off balance or that things around you are moving. As for the back, it could be from how you’re sleeping or sitting. Try to drink more water and stretch gently right after waking up. If this continues to happen, assess your sleeping position among other factors that may affect your general well-being.
