Until and unless you hurt or overstrained the wrist, the two pains should not be related. Pain or soreness in the foot, that eases with time during the day, is generally indicative of plantar fasciitis. The first step you take generally after sitting or standing for a long time or when you get up from the bed is painful. As you start walking the pain clears up. Plantar fascia is a ligament that connects your heel bone to your toes. If it swells, becomes weak or inflamed, it causes these symptoms. After some time, you may feel pain always. The other possibility is osteoarthritis. This also causes pain worse after inactivity—the first few steps always painful.
Other causes of foot pain can be rheumatoid arthritis, faulty arch, ligament tears, fractures, and gout.
Multiple joint pain can be due to fibromyalgia. Apart from fibromyalgia multiple joint pain is seen in hypothyroidism, low Vitamin D levels, Low Vit B12 levels, anemia, Hasimotos thyroiditis, gout (can sometimes cause multiple joint pain), rheumatoid arthritis, osteoarthritis, SLE, electrolyte disturbance particularly those involving calcium and magnesium, parathyroid gland problems, chondrocalcinosis and chronic fatigue syndrome.
Menopause or menopause like condition caused by PCOD is often associated with Vit D and calcium disturbances and hormonal disturbances causing multiple joint pain. Please talk to your doctor regarding these and get yourself examined accordingly.
Please also consult an orthopedic specialist. Meanwhile keep the foot raised. Apply ice pack. Take an anti inflammatory. Take care!
