The lymph glands in my groin and armpits have been swollen for about 4-6 weeks. Ive lost about a stone in weight but have been under stress in my homelife. I have recently started experiencing numbness in my left arm from my elbow to my hand, (the implant is in this arm). It feels constantly numb, but varies throughout each day from dull ache to almost complete loss of feeling. I am 42 years old, I smoke around 10 cigarettes a day. I do drink, but only really at the weekend, around 10-14 units. Lesley.
