<s>[INST] I ve had an almost constant dull ache in my right calf for at least 5 weeks. About 12 years ago I broke this leg in the same area but haven t had any pain until recently. do I need to see a doctor? I woke up this morning with a Charley horse in this calf. Thanks, Tracy [/INST] Hello, A dull ache in the calf with charlie horses can happen due to inadequate stretching or warming up. Decreased fluid intake and electrolyte disturbance can also cause such symptoms. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Praveen Tayal, Orthopaedic Surgeon </s>
