For rhe past 6 weeks ive had a lump on the right side of my neck and recently my lymph nodes have become swollen too.for the past 3 weeks ive had headaches and pain in my face such as under my jaw,along cheekbones accross forhead and eyes and my ears, the top of my head,tbe sides, and the back. I also hmget pain in other areas such as one day i had what felt like growing pains in my right leg when that eventually went away i got a sharp pain pn my left side of ny head and neck when that went away i got it in a pain in my left leg and when that went away i had pain in both my knees. Today ive had very sore left leg and head and face pain im just wondering if this could be cancer?i have a doctors appointment tomorrow about a different issue but will mention these symptoms however im still curious to find out what this is.
