Neck pain and tennis elbow. Elbow.

1. Since the past 10 days I am experiencing excruciating pain on my neck and back region. I was prescribed pain killer (Voveron D) and muscle relaxant (Myo MR) for three days. I did not feel much relief. Then I was advised physiotherapy (interference therapy) for a week. Today I had my third session. What I feel is the pain may be reduced in some parts, but in other parts, it is still persistent. I feel a stiffness. Like, I am not able to put my neck backwards. Front and partial side movement is possible. When I wake up after sleep/generally lying down, my neck and top back region feels extremely crampy and heavy. 2. I fell down from cycle on dec 23rd and hurt my elbow (right). xrays showed no fracture. pain had also gone. however, sometimes ifeel slight pain when lifting heavy objects or wringing clothes. pain is sometimes on elbow joint, sometimes on muscle. doctor said it is tennis elbow. Please suggest homeopathy remedies. Thanks in advance
