Well after 6 long weeks and it not shrinking at all I noticed last Wednesday it felt maybe 20% smaller then within 3 days 85% smaller. It just suddenly shrunk. It's now tiny, about 10% left. I cried tears of relief.
I'm glad I just monitored it and didn't push myself to a hospital check but keep an eye on it, see what your GP thinks. I'm pretty sure mine was right that it was a cyst or something, painless and wriggly ball lump. Whatever it was it took a long time to change and reduce.
I really hope the same happens for you xx
