I've been panicking recently about the lump behind my ear. I've had it for over 2 years. But since November it has been causing me problems only on my left hand of my face, neck, shoulder, back, arm and my hand. Which will feel like a dull numbing sensation. Which really effects half of my tounge really bad. Most of the time half my face feels ill. I'm having bad night sweats. I had a blood test done. I have low vitamin D which my doctors has give me some to take 1 for 15days and then 1 a month. I always had other things low in my blood test results. I feel tired quite a lot. Sometimes I get sharp pains in my leg, I have a bad itch on the inner of my right thigh. Sometimes I find it hard to concentrate and make silly mmmistakes at work. Every now and again if I've worked to hard I get a bad sharp burning pain near my heart. The vains on the left hand temple are bulging our most of the time. I must mention I am also a migraine with aura sufferer. But I haven't had one of thoses for a while. Sometimes my shoulder will feel badly brusied if I leave it to rest for a few hours it will then feel fine. I'm just very worried on what this could be. I had a ultrasound yesterday on my neck. Now just have to wait to hear from the doctors. I am a mum of 3 little babies. I'm just getting really down with how all this is effecting my days. Even taking time to play with my children is causing me pain.
