Usually foot cramps do not last long and can usually be relieved in a few minutes. If you gently massage the local muscles of the calf, and apply warmth and heat, it can be relieved in a very short time. The painful symptoms do not last long, and the painful symptoms disappear after the cramp is relieved. However, some patients have more intense cramps, which often cause local muscle strain, and the pain may last a little longer after the strain. If it is very serious, topical medication can be administered, such as Fotalin emulsion or Yunnan Baiyao aerosol for topical application. After the corresponding rest and medication, the pain can generally be relieved significantly within 3-5 days. Cramps are often caused by injury, strain, calcium deficiency, cold, etc.
