Happy,
I began C shots at the beginning of Dec...it was awful!! Welts the size of eggs...itching to beat the band...and bruises after the welts died down...the bruises last at least 4 weeks for me...the welts are smaller when my DH injects me with the Autoject 2...and the itching is reduced...but the bruises are getting annoying...they turn grey and don't seem to want to go away...it won't look pretty when my DH and I go to Hawaii next month...

I'd give it at least three months or so...make sure to do as suggested above with the depth...I use a 4 for my thighs and abdomen...and a 6-8 for hips and arms. I make sure to warm up the injection sites 5 mintues before injecting, then use a cotton ball to press on the site immediately after injecting. Then I ice the site for a minute or two. I use benadryl cream when the itching begins. i massage the site 24 hours later. I'm going to use a hand massager as suggested above to see if the welt goes down more quickly.
Good luck!!
