Back spasm, tremor in left hand etc.

I have been experiencing upper back issues for over some years. In 2025, I had severe fatigue in my upper back, along with tightness and occasional spasms. After doing regular strength training and physiotherapy for the last 4 months, the fatigue has completely resolved, but the discomfort and tightness still persist. The symptoms are episodic: when the tightness comes, it lasts for many days or weeks, and when it subsides, it stays away only for a few days. When the symptoms goes I feel a very pleasant, relaxed sensation in my back in that process. However, when the tightness is present, I experience noticeable shivering/tremor in my left hand. A few months ago, before this tremor started, I had brief episodes where my fingers would momentarily “lock” for a second. Because of this, I consulted a neurologist and underwent an MRI (spine/brain), which was reported as normal. Kindly suggest me some hospital in Visakhapatnam. I currently stay in a near by town.
