Hi and welcome to HCM. First of all I would like to assure you that you need not panic. Yes, you need to seek medical attention, but it can be easily managed once diagnosed properly. Numbness can be caused due to a lot of factors, primarily, due to bulging of discs in the spinal column, causing pressure on the nerve roots that supply to your foot and hands. Secondly, deficiency of Vitamin D, can cause muscular and neuronal weakness. You may be more prone to this if you are obese or have a lifestyle which requires you to do long hours of sitting or prolonged stay indoors, without enough sunlight. So its highly recommended that you get a BT (blood test) done to find out Vit. D level and calcium levels and also X-ray of Cervical as well as Lumbar spine are recommended to rule out any disc bulges. Once the cause is diagnosed , the treatment will be effective, comprising of dietary management, and Vit. D supplements for a couple of weeks and an exercise regime. Although, you can always start walking to tone up your muscles and strengthen them , which will also help control your weight. I hope this information is helpful to you . Take care and have a nice day:) Dr. Nidhi Sood (PT)
