It's back

No problems during the day when my hands are busy however I am waking up in pain during the night with one or both hands numb and feeling swollen . Not just a tingle in the fingers its a painful numbness in the whole hand but not the wrists. But if I get up move around and do something its clears quickly. I just long to get up in the morning because as soon as my hands are busy I am fine all day. But I am losing sleep. Can you help please ? Is it time for another injection ?
