Male right chest and underarm swelling.

M/33 W:90kgs H:170cms Recently I have noticed there is sloght swelling in my right chest and armpit. Right side seems bit enlarge then left. Noticed this 10 days back. There no pain or any lump as of now what i can feel from touching the Chest or armpit area. However there is some kind mild strain (not always) or tickling pain sometimes. Also, i have shoulder and arm on the day when I work more or use hand more like cooking. I feel i have bad sleepy posture too. History: I had cough issue previously and xray(done on 20th may) were normal and pulmonologist suggested allergic cough as my ige(serum) clia is 260. Currently taking montair 10mg (since last 45days.). Also took other antibiotics and other medicine in last 45day. Recently doc did sinus xray and found sinus problem. Coughing seems to be better then before.
