Two weeks ago I started having sharp, stabbing pains in my right leg, calf area. I have a varicose vein there, and all of a sudden I am having these throbbing pains there. Then, 4 days ago my right eye started having uncontrollable spasms. Then, last night.... I started to have pain in the back of my head, and when I touched it, there was a decent sized lump. It's in the very back, by my neck... Ok, you know where your neck connects to your skull, and on either side there is natually a lump, well the one on the right is swollen and painful (just took ibuprofen). Does this sound familiar, what could be causing this? Should I panic and run to the ER?
