I feel like crap tonight.

It all started with a pain in my back not as low as the kidney but lower than mid way. That lasted several days, then the last couple days i had a weird pain in my neck that i chalked up to sleeping weird.
Well this morning i noticed that i had a VERY sore place on the lower right side of the back of my head. I think it may be slightly swollen but it's hard to tell. But it is really tender.
I also am having a weird crampy feeling in my toes on my right foot. And last night and earlier today i had a strange tingly pain in my left outer ankle.

This is all so weird and the pain on my head is really freaking me out. I'm a nervous wreck.
Anyone ever have anything like this? I will probably have to go the dr. i suppose if it doesn't go away.
I've also been losing an excess of hair the last few months.
