there shouldn't be any problems. i didn't feel anything for about
2-3 weeks
. one thing, the gal that gave me my shots rolled the syringe in her hands to warm up the lupron, which came prepackaged in a full syringe with large needle. she administered the shots slooowly. i barely felt any of the three shots that i got and i think that's mainly because she took such great care. good luck.
