<s>[INST] I am having difficulty when I sit for short or long periods of time walking on my feet. Also, in the morning when I get up I can barely walk on them. It hurts some days feeling like I have needles of some kind. The pain at times appears to be focused around my ankles arch area to heal of my foot at other times. [/INST] Here you have symptoms of pain at feet, arch of feet and heal level after sitting for short or long duration and then when you attempt to walk. Similarly, you also have same pain every day morning after you get up and walk. This kind of symptoms are common with a couple of causes like rheumatoid arthritis, calcium with vitamin D deficiency, or plantar facts (inflammation of plantar fascia). I suggest visiting orthopedic doctor for detail examination and evaluation. Here if rheumatoid arthritis is positive then doctor will suggest for few medications for it and along with this doctor will suggest for physiotherapy treatment. For any other issues also physiotherapy treatment will help you to get relief. I suggest to use soft footwear with in as well outside the house. There is also soft silicon insole available to use with in shoes. You can also do hot water fomentation daily by keeping your leg in hot water. But keep it in floating position so that water can touch the painful sole area.Also, if you get diagnose with rheumatoid arthritis I suggest consulting a dietician to take advice on anti-inflammatory diet to follow it. As well also take advice from physio for few stretches and mobility exercises to follow regularly. Here I have given you general guideline for your pain, but I am sure this will be useful if you follow it properly. Take care. </s>
