For back pain and arthritis, it is essential to first identify the underlying cause through a doctor's evaluation, as this determines the most effective and safe treatment. Treatment is most effective when medications are combined with non-drug strategies like physiotherapy, exercise, and weight management.

Severe leg muscle pain with stiffness, cramps, and occasional foot swelling can be due to muscle strain, low mineral levels such as calcium or potassium, or poor circulation. Overuse, dehydration, or long-standing hours can also worsen it. Try to stay well hydrated, do gentle stretching, and use a warm compress to relax the muscles, and avoid overexertion. If the swelling or pain keeps coming back or gets worse, talk to your doctor to find the exact cause and treat it properly.

Body chills with back pain and pain going from the hip to the toes may be due to a viral infection or nerve-related pain along with body aches. Take proper rest, stay warm, drink plenty of fluids, and use a warm compress to ease muscle and back pain. Avoid strain and keep your movements gentle. If the chills continue, you develop a fever, or the leg pain is severe or not improving, consult your doctor for proper evaluation.

Fever with a strong headache and joint pain, followed by weakness and body aches, is usually due to a viral infection like the flu, where body aches can continue even after the fever settles. Take proper rest, drink plenty of fluids, and eat light food to help your body recover. You can use simple pain relief if needed and avoid strain for a few days. If weakness or pain continues, or fever returns, consult your doctor for proper evaluation.
