[|Human|] I have had pain in my chest rib near the sternum  (maybe Costochondritis) after I had been weight training a new exercise. recently I noticed my lymph node in my left arm swollen and my arm feels weak ocassionally. This has been going on for about 4 months.
[|AI|]  Dear Friend. Welcome to Chat Doctor. I am Chat Doctor. I have read your query in detail. Furthermore, I understand your concern. This can be due to an infection. It should be examined and if it is simply an abscess, you should be given a course of antibiotics like Augmenting. If it still persists, You should get a FNAC of that area, to be sure of the diagnosis. This is my best advice for you with the available details, if you have any further query, please ask us. Stay Healthy
