So, about six years ago, I noticed a lump on the back of my neck. It was about the size of a pencil eraser and painless. For one reason or another, I thought nothing of it. The lump was there for at least 4 years. Now, I'm not sure if I just stopped noticing it, or if it's back, but started feeling it again about a week and a half ago. It's under the skin on the left side of my spine (but is not a PART of my spine- I can move it around). It's still painless, and you can't feel most of it unless you apply pressure to the spot.
I went to see my PCP a couple of days ago. He literally talked to me for about three minutes. He felt the lump and told me that since he doesn't know what it is, he's just going to assume that it's nothing. He also told me that he doesn't know if there are lymph nodes in the back of the neck. Both of these statements kind of alarmed me. Just because he doesn't know what it is off the bat, we'll assume it's nothing? He doesn't know if there are lymph nodes in the back of the neck?
In addition to the lump, I've also been experiencing other problems. I'm no stranger to headaches, but they've been coming a lot more frequently lately. Also, the head pain is on the left side of my forehead instead of the middle, where it usually is. More often than not, the headache sticks around for two or more days.
I've also been experiencing fatigue throughout the day for several years now. I never thought to connect that to the lump before, but I think I've been feeling this fatigue since about the time the lump first showed up.
This is kind of gross, but I'm also having problems with bowel movements. For the last week or so, every time I go I get a really sharp pain around the opening. Then there is blood on the toilet paper. I've never had this before.
Lastly, and maybe not so significantly, I just don't feel right. I feel sick all the time. I'll sleep for 12 or so hours and still feel tired. It's hard to explain...my body just doesn't feel okay. It's not really hurting (besides the headaches) and I don't feel like I'm getting a cold or the flu.
Should I go to another doctor and be sure to tell him/her all of this? Do I have nothing to worry about at all? Am I losing my mind and thinking about this too much??
