For anyone who experiences random numbness for periods of time I would recommend getting an MRI, diagnosing MS early can help manage is better. I was diagnosed a while back with MS and the numbness is exactly like what many of you have described. Especially during "relapsing". The condition is diagnosed quickly and can be managed to almost non existence if done properly. So I would not get yourself worked up even if it is MS.
One thing I will note that in my particular case with MS, I have never had numbness anywhere above my neck, so that might be a sign that it is something else in your case, but I do not know if that is relevant or not. I know everywhere else on my body is fair game when my MS decides to creep back in and take a swing at me.
I have burning, tingling, and numbness that move around from feet/legs and hands/arms. Also sometimes in face or left thigh. I thought it was really strange that it would hop around. It seemed to me that a disease like MS would mean the symptoms would stay where they were and just get worse. I did some checking around and found this data:
Paresthesia
"The skin sensation of partial numbness or "pins and needles" or a type of "burning", "tingling" or "creeping" sensation of the skin, is known as a "paresthesia". Symptoms may start as a tingling (paresthesia) and change to a numbness, or there may be a combination of decreased sensation (numbness) but with heightened sensations at certain times or with stimulation. Any type of tingling, burning, or numbness is usually a symptom related to a sensory nerve being damaged, diseased, or injured. Causes depend on the exact location of the paresthesia sensations, but typically include a physical nerve injury type condition (e.g. a nerve entrapment or some type of pressure being applied to a nerve directly or to the spinal attachment of that nerve), or a disease condition affecting the nerves (e.g. neuropathy, diabetic neuropathy, multiple sclerosis, diabetes, and others). Having these sensory symptoms in multiple locations, or the recurrence of similar symptoms in different locations is a hallmark symptom of multiple sclerosis, so your doctor will likely ask about the past history of similar symptoms to assess the likelihood of multiple sclerosis as a diagnosis (see symptoms of multiple sclerosis). Any of these tingling or numbness symptoms are more than just annoying; they can indicate a serious medical condition and require prompt medical diagnosis by a professional."
It was a definition I found from some online medical site. (Sorry, I don't remember exactly where.) Anyway, it was helpful to me to understand better what was happening to me. I will post this as it's own link so others see it.
I hope it helps you too!
My pain and tingling moves around all during the day as well. My PCP said that is what MS does. Am I wrong?
