I have been experiencing numbness in my left foot. It comes and goes sometimes throughout the day and sometimes it is completely normal. This has been happening for the past year. At night, when I lay down the back of both my calves feel like they are rhythmically pulsing only when lying down. I am freaking out that it might be the start of MS. I am a 36-year-old female. I have also had a mild case of mono (age 20) and have read that can increase my chances as well as being of Scottish descent. I very occasionally have neuralgia in a spot right above my collar bone and it is always in the same spot and very random. The shock lasts for about a few seconds then disappears. This has been happening for probably for the past seven years. I have also read this can be an MS symptom. I am trying to decipher if my symptoms are anxiety-related or if I truly need to be concerned with MS?
