I just now discovered a cluster of small lumps in the side of my neck, principally on the right side. I was giving myself a neck massage and thought I felt 3-5 spider or mosquito bites on the right side and one on the left...only they were not sensitive to palpitation and seem to be in the blood vessel cluster itself. I had a slip on carpeted stairs about a month ago and gave myself an impressive bruise just above the outside of my elbow. There was also a half-chestnut size lump there I assumed was as much lymph as blood and it did subside over about 2 weeks. I am currently between insurance and not panicky, but am somewhat concerned I may have migrating blood clots. The very ball shaped lumps are quite firm, and I would say roughly bibi or pimple sized. Should I be seen at the ER?
