<s>[INST] I just had a situation where I suddenly had a very sharp pain on the outside of my right calf, and it intensified each time I attempted to put any weight in it by walking. The initial level of pain only lasted about 5 minutes and began to subside. Now i am experiencing a cool feeling in the same leg. FYI - I am just recovering for a bad case of Shingles, but it wasn t on the same side of my body as the leg pain. [/INST] Hi, Get your colour Doppler of the affected leg done it might be blockage of arteries or veins in your leg. Take it as a serious situation and get your Doppler done as soon as possible. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Jaideep Gaver, Orthopedic Surgeon </s>
