Hi Soumya garu, nothing to worry about your Grand father. Joint pains (Arthritis) is a common condition that happens when the protective cartilage between the joint and bone breaks down, causing pain in those joints, like hands, knees, and hips. Pain showing up as people age is a real thing. More than 50% of people over the age of 65 have some level of joint pain.  Joint pain is dependent on many things such as family history, physical activity levels, environmental conditions, history of injuries or trauma. There are two main and most common types of arthritis. One is Osteoarthritis which is often called wear and tear arthritis because it comes from using the joints over time or after an injury.  Another one is Rheumatoid Arthritis, it is an inflammatory condition where the immune system attacks the tissue that lines in joints.  Homeopathic medicines are definitely suggested for joint pains, especially for early cases where the medicines can slow down the degenerative process and offer considerable pain relief.  Homeopathic medicines can reduce pain and improve mobility of the joints. Some of the commonly used homeopathic medicines for joint pains are; Rhus Tox, Bryonia, Arnica, Calcarea flour, Mag.Phos, Cimicifuga, Radium bromide, Bellis per, Hypericum, Symphytum etc. Better to take doctors advice before taking medicines.
