Hi, I was unable to stretch my right arm fully as there was pain in veins. There is a presence of lump in my armpit. I consulted a doc and he diagnosed as vein injury and presence of an infection as crp in blood was high (19). I am taking antibiotic (augpen 625) for a week now. Though the pain is reduced a bit but the lump is not totally gone. Please advise if i'm diagnosed right or there is any matter of concern.
