Hi welcome to Health care magic forum. Your mother had needle biopsy
and resulted in severe pain
along the hand . Previously when it is done there was no pain at all. Whether you have contacted the doctor done the procedure or not. Because he will be knowing more about it .
The needle would have touched the nerve
, or a blood vessel during the procedure, of course it is natural, but some infection has developed and causing pain. If drugs are used, he will get relief of infection and pain.
Besides i advise you some diet recomendations as Avoid taking more of potato, other tubers, pulses, tomato, fish, other sea foods to avoid more pain.
Take more of green leafy vegetables, sprouts, egg, milk, meat, fruits, juices, and dry fruits to have enough blood, general health, resistance, and stamina to bear the pain.Wishing her a quick recovery and thanks for calling.
