My mother who is 43-year-old, often gets a tingling sensation in the back. What can be the possible reason?
—R Senthil, a resident of Alwarpet.
Any such sensation such as a tingling sensation or pin sensation in the back can be due to the underlying nerve issue. Such sensations are called paresthesia and can be due to minor infections, spinal injuries, spondylitis, fibromyalgia and vascular malformations. Pain relievers, wet compression, anti-inflammatory drugs and exercises can help reduce the sensation. As the symptoms can vary, the consultation from a medical practitioner is necessary

What is secondary progressive multiple sclerosis?
— Abhishek K, a resident of T Nagar
Secondary progressive multiple sclerosis is a later stage of multiple sclerosis. Instead of having symptom relapses and remissions, a person’s symptoms steadily get worse over time. Multiple sclerosis (MS) is a progressive condition that causes the immune system to mistakenly attack the nerve cells in the central nervous system. Most people, but not everyone, with relapsing-remitting multiple sclerosis (RRMS) will eventually develop secondary progressive multiple sclerosis (SPMS). Because of advances in current treatment, fewer people go on to develop SPMS than before, and it takes longer to transition to SPMS..
