You probably should have had a doctor take a look- have you made sure any tentacles were removed? If you have any open sores, make sure those stay very clean and you can apply first aid cream to those areas. You may want to ice the spots if they are painful. If anything gets worse, go to your doctor right away- if it were me, I'd just set up an appointment to ensure that you have all your bases covered as far as tending to the affected areas.
