Just looking for advice. I found a lump on my groin around April time when straight to doctors  has it was painful at the time. 2 doctors  examined it both said the lump could be a swollen lymph nodes. Got refferd for a ultra sound scan 3 weeks later. Got my results 2 days after to be told very enlarge lymph nodes change to tissues and looks unusual. Got refferd for a urgent mri pathway to cancer suspected sarcoma. Had my mri on Wednesday still waiting on My result was told it could take about a week for results. now the lump isn't so painful just a dull ache soft in middle but hard around edges doesn't move.also the skin where lump is keeps changing colour it's keeps getting redder or going purplish.  Doesn't the skin change colour overtime?
