I have two problems that have cropped up within the last month.  First a small lump showed up under my left arm, then it went away, the next day it came back and went away.  then it came back got large and hasnt left for a month now.  Its painfull on and off and and is now interfering with my arm movement. everything I try on it seems to reduce the size, but usually overnight it gets big again.  help!   Second thing is I lifted something 3 days ago and twisted on my left leg while doing so and I have had trouble doing anything since.  Help!
Hello rearward welcome to Chat Doctor.come have evaluated your query in details .* Left arm lump seems to be sebaceous cyst, lipoma or other soft tissue lesion.  While primary relief can be with analgesic tablets, must get final diagnosis with examination by consultant surgeon.* Leg pain is in concern with ligament sprain or muscle stretch, local application of heating pad, analgesic tablets will take care of it. Hope this will help you for sure . Wishing you fine recovery. Welcome for any further guidance. Regards .
