I feel like a reject goat keeper...Evidently, when i gave our doeling her 2nd CD&T booster, I accidently got into the muscle because she has a fist size lump there now on her shoulder. I gave her the shot a week ago today and just noticed the lump today although it could have been there longer and I missed seeing it. She was born 4/30. It doesn't seem to bother her...not tender to touch or anything. Our 4-H leader said it may reabsorb or may cause a cyst and have to be lanced and drained Is there anything I can do to prevent that from happening? And, could it be anything else? TIA!
