I'm a 21-year old man. In mid-July, my left arm went both weak and numb. I found this out while weightlifting, and I simultaneously strained both my bicep and pec. After one week, I went to the hospital and received an x-ray. It was negative, but I was referred to an orthopedist. He ordered an MRI on my cervical spine.
Prior to the MRI, my left leg went weak and numb. So I received a lumbar MRI. Both were negative, but showed slight pressure. Went to a neurologist and received an EEG which was showed just a slight difference. By this time the numbness was gone and replaced by constant tingling sensations that had spread to my left side of my face, and I had regained about 80% of my strength back in both my leg and my arm. I was then referred to a nuerosurgeon and received an MRI on my brain and blood tests (for Lyme). Blood was negative, but the MRI and subsequent MRIs show a slow or non-growing dime sized spot on my left thalmus, which wouldn't necessarily indicate anything for if it was on the left side it should affect my right side.
As of right now, my strength is about 80% on my left side. The tingling sensation is constant. My coordination on my left side has improved tremendously but still lags compared to where it used to be. I'm also having episodes dictated by activity of dizziness/pressure almost a "fog" in my head. This starts after light cycling after 10 minutes or even sweeping and then walking up stairs. It's been three months with no diagnosis and no treatment. Any thoughts?
