Hello, your filial piety to grandma is very rare and very touching. I recommend this massager to you. The price is in the middle range, but the effect is also very good. This massager is an ultra-light wave hot compress massager. The massage head is made of nano high-temperature resistant materials, which can be heated quickly by carbon light waves, reaching about 50 degrees in a few minutes. Combined with the kneading function of simulated human body, it produces hot pressing effect on human acupuncture points and muscles, forming a particularly good health care effect and opening up human meridians and blood vessels.
Hot compress can relax muscles, dilate blood vessels and promote blood circulation. Therefore, it has anti-inflammatory, repercussive, analgesic and warm-keeping effects. This massager has the advantages of long duration of hot compress effect, low price, high curative effect, and most importantly, simple operation. External application on the affected part does not affect the work, so it can be used at work and can be massaged and hot compressed at the same time. I hope your grandmother will recover soon!
