I have this cut on my heel from boots rubbing yesterday. I cleaned it and put a plaster on it and it has been fine since then. I wore very soft back shoes today so it did not rub. But tonight when I lie down it's quite painful. Every so often it does a little throb. I have a compeed plaster but not sure if I should use it as it's not exactly a blister. Should I use the compeed or just a regular plaster? Any tips for pain relief? Thanks
