My guess is that the neoprene girth caused that as it appeared over night after using the girth. If the girth is too tight & the saddle is quickly removed after riding the blood & other body fluids will rush back into the area that was compressed (rebound edema) & can cause the swelling. Same concept as why we should slowly loosen girths after long rides to prevent the back from swelling.
If this is what happened there are a couple of things you could try to dissipate the collected fluid as if left alone it will take a while to leave on it's own due to the location.
1. Epsom salt poultice to try to draw out the fluid
2. Resaddle the horse (if not painful) with a soft girth cover on, snug only, not tight enough that you would ride with. Leave saddled a while then slowly loosen a tiny bit at a time. This should help push out the extra fluid & allow only slow filling.
Don't feel bad, many people make this mistake when first using neoprene as it never 'seems' tight enough so we over do it. Ask how I know this!
