About 10 days ago the gland in my neck started swelling. A couple of days later I started getting lumps on the back of my head. Thay don't hurt, but I have three uniform lumps. Two on right side, and one on the left. They aren't ingrown hairs, or cysts because there is no pain, redness, or warmth to them. A couple days after the lumps on my head, my knees started getting stiff. Like I had done a million squats. Within a day, the backs of my elbows, wrists, ankles, neck, and finger and toe joints seem to have all gotten stiff and uncomfortable. When I fully extend my arms it feels like I threw them out playing ball. Fingers and toes just feel swollen and stiff to close. Visually I look fine, just have the lumps in my neck and head, but physically I feel like I got hit by a truck.
I had some left over pennecillin so I've been taking that for three days now, and still no relief. If anyone has any ideas, I would greatly appriciate the input.
