My father, aged 71 ha been suffering from spondylitis almost for a decade right after the retirement. Tried homeopathy but soon he stops taking the medicine, it starts again. Then visited orthopedic Dr. Who advised to do physiotherapy for the lumbar and cervical spondylitis as x-ray reports suggested. Following the same he underwent physiotherapy for a long time and eased the pain to a considerable extent. This time he is mostly troubled by the pain occurred in the face of the leg near the ankle only while walking. On 6th july it went bad to worse and had to rush to a orthopedician. But this yields no result and the pain gradually went up and now revolving around the back of the right knee (muscles/vein) for which he is not able to walk or lift/turn the body up from the bed. Matter goes bad to worse when he sits in the toilet seat and put the foot in staircase.
