..glad it worked out.
have to remember you are injecting oil deep into your muscle that is not normally there
it takes a while to get used to it and you will have pain and discomfort for a while.
and if it is ug gear and you dont know whats it in then it may be hi BA which is used to keep it clean.
either way if it swells a few days later dont panic until you are certain its an infection.
which believe me there will be no question about it if it happens.
but yes, pain to some degree is normal after experience you will be able to tell what is normal pain and what isnt.
