Big A question for you.I am trying to find out if this is what you call a "Lump" or if its local swelling. I massage hard but it seem as thought the majority of the muscle head swells up real tight, to the point its hard to get the oil in next go round. it seems to go down some by the next injection but not all the way. Its not defined like a rock or a marble. Its more like half of the muscle head swells real tight and hard. I just want to know if this is what you call a "lump" and if so, i guess i am not massaging hard enough. Example if i inject in the inner head towards the top it swells about half of the head and it get really hard. Thanks.
