<s>[INST] Hello, I get these like 2 inch long sunken areas on my feet and sometimes legs. These sunken areas are red and with a stinging pain. I can lie down and elevate my feet and they go away in a couple of minutes. I am being treated for water retention with swelling to my feet and legs. [/INST] Hi, It could be pitting oedema caused by hypertension or any other water retaining disorder. It must be investigated & cause found out. then only treatment will be possible. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Nirmal Chander Gupta, Orthopaedic Surgeon </s>
