What causes a lump and pain while lifting an arm?
Patient: Hi, yesterday after playing 3 hours of basketball, I noticed a pain in my armpit. Everytime I try to lift my arm it starts to hurts, I also noticed that I have a lump in the area that hurts. Please tell me what s wrong and what I have to do to stop the pain. Doctor: Hi,  This might be a case of frozen shoulder, tendon injury /inflammation, shoulder dislocation.  You can get cold compression to reduce the pain and swelling and get an X-ray shoulder joint done for confirmation.  Hope I have answered your query. Let me know if I can assist you further.
