My 73-year-old mother has been suffering from this disorder for many years. She experiences an irritating and highly uncomfortable tingling sensation all over her body. She becomes very restless when this tingling sensation occurs.When this disorder first started, the tingling sensation occurred regularly. For a long period, she was on allopathic medicine (Tancodep plain and Milaret 5). Although she no longer feels this discomfort regularly, but few days ago, after 3-4 years the irritating tingling sensation returned and lasted for 3 days. Currently, she is fine. To give you an idea of how uncomfortable this tingling sensation is, it feels similar to the sensation experienced when a limb has been in a resting position for a long time. Please suggest a suitable medicine to get rid this tingling sensation.
