Arthritis in my leg and joint pain had previous injuries years ago and on rainy or cool days i get joint pain?

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see a doctor, preferably an orthopedic surgeon. For relief of pain, you may take acetaminophen, no more than 4 g/day, no alcohol. Do aerobic exercise regularly to maintain muscle strength and flexibility. Wish you good health!

It is common for joint pain to flare up with weather changes. Changes in atmospheric pressure will cause pain in your joints.
