Are numbness and paresthesias constant in ms or can they be intermittent?

MS paresthesias: Multiple sclerosis parasthesias are abnormal sensations due to nerve damage by demyelination lesions. Lesion means sensation. It is always there in mild, moderate or severe forms. The severity depends on the relapse, remission and use of analgesics. The patient may feel severe at relapse and not so much in between. But it is there. The numbness or tingling is the first sign.

Can fluctuate: Depends upon ambient temperatures, fatigue, use of alcohol, medication interactions, infections, stress, etc. Make sure that your MS disease agent is potent and well tolerated.
