Two days ago I have noticed a blue bulge (little bit painful) on my cheek but I did not member what I have beaten. Today again I got one more bulge which is the same to the previous one- as I remember, I have not beaten anything today.
Therefore, I am worrying that it might be a symptom of any disease. Could you please advise me on this? If helpful, I can send a photo of this bulge on my forehead. Please help me. Thank you very much.
