Hi and thanks for the query, The feeling on cold would depend on the type of initial therapy she received, the ambiant temperature and simple changes in sensations. Some other person needs to touch different parts of the body to actually ensure that this feeling of cold is objective. However, feeling cold could simply mean there is a reduction of blood flow to the periphery. This is caused by contraction of arteries, a normal physiological response. It would have been more disturbing if other signs and symptoms like lack of sensation or uncontrolled bleeding were associated. But if the sensation is still ok, normal muscle function and she feels pain, it means a normal state of nerve function. I do not think she needs to panic now. Taking her medications, analgesics and antibiotics if needed should be sufficient. Persistence or aggravation of the pain after a few days would compel her to seek a reevaluation from her primary care physician. Thanks and best regards, Luchuo, MD.
