What could cause arm bruising?
Patient: Quick background. Diagnosed with Hodgkin’s Lymphoma on January 13th, started Chemo on January 27th, finished Chemo on June 29th. PET-scan on August 22th was all clear & blood work on the same day looked good according to my Ecologist. My question / concern. 3 days ago my right bicep started to ache…that night, about 2 inches up my arm from my bicep it felt like I was punched. Now I have a huge bruise on my arm and I do not recall getting injured on that arm at all. What can this be? Doctor: Hi,  It should be investigated. It could be a reactivation of the original disease or hopefully an infective process setting in.  Hope I have answered your query. Let me know if I can assist you further.
