<s>[INST] Since yesterday evening I have had a numb finger tip on middle finger of left hand. It also goes slightly done the sides of that finger. It feels a little like it might spread to the other fingers on the hand. If I touch anything withthatfingeri get pins and needles. Started after carrying some heavy shopping. What is it? [/INST] Hello, As you carried heavy shopping bags this has led to a spasm of the muscles leading to nerve entrapment and so does the symptoms of tingling and numbness.  Doing hot water fermentation to the cervical spine, an exercise which includes strengthening of the muscles of the neck and triceps is advised. Hope I have answered your query. Let me know if I can assist you further. Take care Jay In Chat Doctor.  </s>
