I forgot to tell you all one important thing. I wear a finger cot on the index finger of my right hand. This helps to pull the needle out.
Finger cots can be bought at quilt stores for tons of money but you can buy a box at a medical supply store for about $2.00. Wal Mart and drug stores also sell them in small quantities....best to try their for the sizing.
Long ago, finger cots were used by nurses, to insert suppositories.
