The common causes of medial calf cramps are usually muscle strain and muscle spasm, which are usually caused by muscle aches and pains due to strain, cold, or long-term squatting work, excessive walking, climbing hills, stairs, etc. Most of the pains and cramps are caused by the accumulation of inflammatory substances, lactic acid accumulation, etc. Calcium deficiency can also be caused, and attention should also be paid to exclude cramps and pains caused by herniated discs and vascular diseases of the lower limbs. If there is severe osteophyte or other serious infection, it can also cause medial cramps and pain. In this case, it is necessary to pay attention to rest, reduce activities, avoid walking too much, elevate the affected limb, pay attention to hot compresses, and apply topical medications. If the cramps and pain are severe, analgesic medications can also be used. If there is no relief or if there are other accompanying symptoms, such as redness and fever, radiating pain in the lower limbs or localized masses in the knee joint, you need to go to a regular hospital for examination.
