I hope you can help. My one and a half year old grandson started with a absess under his arm. When it was drained to the doctors surprise the fluid was clear. About two days later his testical swelled up with fluid and that was drained. To their surprise again the fluid was clear but there was blood on the lining of the testical. About four days after that he started with these fluid pockets on his head. They were not that big but painful to him if they were touched and they would bruise almost immediatly after they are formed.. Everytime he got one, we brought him right to the doctor. They had no idea what it was. These bumps are much bigger now and they swell up and cause blood under the scalp but and on the outside of the skull. There is no bleeding in the brain it self. Nobody can figure out what is wrong. Can you please help?
