Hello. I have had a cold allergie for the past week. Stuffyness, low fevers, yellow nose drainage, etc. But last night i felt my shoulders sore as I bathed. Then I felt a lump. I checked it again, now under the light and it was hard and red, and painful. Ive had this all day today. The lump seems less hard, but the pain is worst. It feels like it has spread to my right chest and the right side of my back close to the shoulder blade. What can this be? I know a doctors visit will clear any doubts, but what are the statistics? I am a 35 year old female
