Blood-phobic (n = 81) and injection-phobic (n = 59) patients fulfilling the DSM-III-R criteria for simple phobia were compared on a number of variables. There were no differences between the samples in age at onset, age at treatment, marital and occupational status, history of fainting in the phobic situation, and impairment. Higher proportions of blood-phobic subjects than of injection-phobic subjects reported having first-degree relatives with the same phobia (61% vs. 29%) and reported fearing that they were going to faint in the phobic situation (77% vs. 48%). In both samples, these proportions were higher in the subgroup with a history of fainting. Injection-phobic subjects rated 2 of 11 physiological items higher than did blood-phobics subjects, but the groups did not differ on behavioral variables. Overall, the similarities were more marked than the differences, and it is suggested that these two specific phobias should be regarded as one diagnostic entity.

The blood is a result from hitting a vein with injection...when you inject pull back on the plunger to check for blood return. If there is blood change the needle and reinject in a different spot. Hitting veins is inevitable but its usually nothing to worry about.

it's normal

site rotation as dbolz says; just be sure to get 25g 1" for the quads (22g 1.5" is asking for pain)

always have the swab ready and maybe bandaids as well
