Why do I have foot and back pain in the morning?

Swelling in your leg can occur due to the injury. It is your body's way of safeguarding itself. If the swelling does not subside, try elevated rest, ice pack application, and wear a compression bandage. These measures can help you swell less and thus, ease your pain and make your exam successful. 

The movements which cause dislocation after hip replacement are:

a. Bending and leaning forward 
b. Sitting on low chairs, low bed, low toilets.
c. Crossing the knees
d. Lifting knee higher than your hip.

Some conditions can be resolved through rest and physical therapy. Be sure to tell your doctor what you’re experiencing, such as pain or difficulty moving. Knowing the cause of the problem can help determine whether or not an operation is required. You must follow the advice of your physician regarding the most appropriate treatment for yourself.

Your legs did not develop properly at birth, which has caused your feet to form abnormally and made it difficult for you to move. Treatments like therapy, braces, or surgery could help improve your condition. These treatments may help you walk better and feel more comfortable. Because your limbs do not fully form, your feet are bent, and movement and balance are difficult. However, with the right therapy, braces, or surgery, your mobility and balance might improve based on your specific case. While this issue has made movement challenging, it does not mean you are helpless.

Maybe there is an infection in your foot. When your skin is pierced, bacteria may enter and cause swelling. The symptoms you are having such as feeling sick to your stomach (nausea), throwing up, being unable to have a bowel movement (constipation), headache, and having a high temperature could be due to the infection moving around. Quick treatment with antibiotics and other drugs from a doctor is needed so that you can get well soon.
