Altered sensations such as "pins and needles" or a hot or cold sensation on the skin occur if the nerve that conveys the sensation is not compressed and functioning properly. Pain covers up these feelings before surgery and, only after the surgery when the pain is resolved do these feelings start to be noticed by the patient. Numbness in the leg or foot is often the symptom which takes the longest to resolve, taking a few months to disappear or become fairly tolerable. However, sometimes the sensations mentioned above can be permanent.
I get intense shooting pains on the left side of my head, just above/around the ear, and I also have a very sore and stiff neck.
It sometimes feels like my heart beats irregularly and very hard.
I have dizzy spells and sometimes feel very foggy.
My legs and arms feel “weak”, not all the time, but frequently. My legs all the way up the thigh and down to my feet feels like they are tingling, the feeling you get just when your feet or legs fall asleep and then start to wake up, kind of an aching tingly feeling and it also feels like it hurts “inside the bones” in my legs.
However, there are other types of numbness that a patient may feel that are not specifically a consequence of the incision for knee replacement surgery. Some examples include a radiating numbness down the leg from sciatica or diffuse numbness of the feet from peripheral neuropathy (typically associated with diabetes). Certain complications from a peripheral nerve block peripheral nerve block can cause numbness or burning down the leg. These types of numbness should be evaluated by a physician to determine the cause and decide if treatment is necessary.
