I wouldn't normally post medical problems on a computer forum, but this one is out of interest rather than worry. Last Friday (5 days ago) a big lump suddenly appeared on the side of my forearm, just above the elbow. For a few days it was quite painful but the pain has subsided a lot. Most lump problems I read about are small and appear gradually, but this one is over an inch long by half an inch wide and just seemed to appear. It's really hard (feels like bone, in fact, though it's transverse to the bone). I assumed it was a bite. I never had a fever or felt unwell. It was red to begin with but that seems to have gone now. I would assume it's all over, but I think the lump is as big as ever. Just wondering if anyone has had experience or if there are any doctor's in the house?
