<s>[INST] I am getting Charlie horse pain in my fingers and calfs....especially during the night. I am 75 and have numerous medical issues but these just started since my dr limited my fluids and potassium, because of kidney failure...is there anything I can do to relieve this pain. [/INST] Hi, As first-line management, you can take analgesics like paracetamol or aceclofenac for pain relief. If symptoms persist, it is better to consult a physician and get evaluated. An arterial Doppler also required to rule out peripheral vascular diseases. Hope I have answered your query. Let me know if I can assist you further.
