I have a lump on the left side of my neck that has been there for five or six months, creating headaches,pressure behind my eyes and in my head painful swelling around the lump and left side of my head neck area. electric shock like in my back and shoulders that creates muscle pain, numbness in my toes and fingers at times. Weakness in my legs at times, also very little energy. I am 26 years old and have done physical labor. I do not have a primary care physician. Where should I start, what should I do.
