[|Human|] I am male 54 yeara old. I have an indentation in my arm pit and get pain in the shoulder and down my arm. At first I associated this with walking my dog a giant schauzer she pulled and almost riped my arm off and then this occurred. Of course the first thing i think of is cancer. I am scared.
[|AI|]  Hi and welcome to Chat Doctor, thank you for your query. Well, cancer is the last thing to think of actually ABD in most cases this is just benign lymph node swelling or there is swelling due to trauma or just foliculitis- you should just wait and see will it progress in size and then further tests can be done. If this is lymph node then you probably had some infection, and it should pass in few weeks. If there is redness and pain then it may indicate inflammatory processes. Wish you good health. Regards
