i'm glad you got that spot on your hand frozen. it's better to get those suspicious lesions off before they can turn into something serious. regarding your blister. don't "drain" it. don't pop it. leave it alone. the clear liquid you see coming out is a sign of the body trying to heal itself. that liquid contains proteins and cells of other types the body needs to repair the damage caused by freezing the skin. if you continue to drain off that fluid your body will have a more difficult time repairing itself. a better idea is to apply some antibiotic ointment and apply an adhesive bandage. then leave the wound alone for several days. keep it dry as much as possible. when showering either leave the bandage in place or remove it but do not scrub the wound. simply allow water to flow over it. then re-apply the bandage. after about 5 days of being left alone you should notice a scab or some other "dry" type of healing going on. at that point you can leave the bandage off. and don't pick the scab. wishing you well!
