[|Human|] I have developed a strange throbbing, heavy sensation in my left leg from the knee down since 7 o clock this evening. I have pain in my knee, calf and ankle. My leg feels weak when I walk on it and I have a tingling sensation from inside almost a bit like pins and needles. There is no noticeable swelling or redness.
[|AI|]  Hello, As you have a sensory disturbance I will ask you if any other underlying condition is bothering like hypertension or diabetes. If so then we need to look for it.  If not then try observing the skin if there is any discoloration, that may be the signs of the varicose veins.  Need a proper ruling out of the same symptoms. If all of the above is not existing then u suspect this to be a nerve root entrapment in the lumbar spine.  Taking up and x-ray or MRI will be guided to rule out any possible causes. With core stability, strengthening the spinal muscles and the lower limb muscles as a whole will improve the condition and reduce the symptoms. Hope I have answered your query. Let me know if I can assist you further. Take care Jay In Chat Doctor.
