For the past two weeks i been having pain on my left shoulder, arm, hand and last two fingers. accompanied with that i have a lot of chest pressure and feel like that when i take a deep breath i don t get the feeling that i am supposed to have. Recently, i had a throat infection, inflammation and a stomach thing ( I had diarrhea for 3 days).I had labs done a week and a half ago. Now, i just noticed that i have a red spot on left arm. I have other spots like that one, this one spot is new. I went to the doctor and he said i had my ribs inflammed. what do you think could be going on?
