I'm sorry to hear all the pain your dealing with right now.I definetly think you need to seek advice of a doctor,there is no doubt about that.The numbness on one side is what caught my attention.Have you heard of Bells Palsey? I had an episode of it when I was 15.It caused major migraines,fatigue,light sensivity,and amoung those-numbness on one side.I was numb on the left side of my face.One doctor insisted it was just migraines, so I went to another-and thats when they told me thats what it was(Bells Palsey). I could have taken steroids for it but my doctor said it would go away on it's own within a few monthes. At 15 I opted for that because I heard the word "weight gain and steroids" and completly freaked out. It did go away after time.And since I have been dx with Migraines and Vertigo.I have also been dx with IBS and Ulcerative Colitis.Anytime you have pain that keeps you up at night you should tell a doctor...it really sucks,I know.I am only giving you my experience,but I am not a medical expert...it could be anything.Maybe a cat scan could help figure things out too. Take care and let me know how things go.
