Can I Get Relief for Sudden Joint Pain?

Your mother appears to be suffering from arthritis for a long time. The pain in her arm may be caused by joint inflammation which indicates that it’s a nerve problem if she experiences discomfort in the stomach too. When people have arthritis, sometimes they undergo a situation where nerves get affected hence feeling pain in different body parts apart from those with affected joints. To minimize the pain she is going through she should do gentle exercises, use warm towels if possible, and get drugs prescribed by a physician. 

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.

Knee crepitus can be from multiple causes. Painless crepitus can be ignored. So, I won't advice for crepitus knee treatment as such.. Crepitus from knee cap problems can be cured with hip and knee strengthening. Crepitus from cartilage irregularities or loose pieces often need minor keyhole surgery. Painful crepitus from arthritis is initially treated with physical therapy and surgery when therapy stops helping. 

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. 

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