Left Hand Pain: Muscle Strain or Nerve Issue?

It seems like you may have some symptoms which could mean many things. Pain everywhere, feeling bad a lot, always being worn out, and sweating at night are all signs of different illnesses. A virus infection might be one cause but so could an immune system disorder or even just stress alone. You need to see a doctor so that they can find out what is going on with you exactly--and then give feedback that is helpful for treating whatever this turns out to be.

The treatment for the lesion depends on the type and location of the lesion, the symptoms experienced and the overall health of the patient. Accordingly, treatment options may be suggested which includes surgery, chemotherapy, medications, occupational and speech therapies etc. 

Losing consciousness can occur when the brain receives insufficient oxygen or blood supply. Perhaps you sustained a head injury after falling. Signs may include feeling lightheaded, weak, or even disoriented just before losing consciousness. You should see a doctor who will examine you and tell you what to do so you do not put yourself in any danger.

Your grandfather might be experiencing tongue problems acquired after a recent stroke. This is the term for dysphagia, which is difficulty in swallowing and speaking. Amazingly, he can now open his mouth and move his tongue slowly. For him to make a full recovery, speech therapy might be useful. Exercises and techniques help in the aspect of toning control of the tongue and swallowing, adding to the general treatment of dysphagia. 

It’s always very worrying when a child’s seizures are as intense as you say and don’t seem to be affected by any drugs. This needs attention right away. When medicine doesn’t help, sometimes surgery will. The cost of treatment may depend on different things and I think it would be good for you to talk with the staff about that. 

Could be related to a complex network of nerves in your head and face. One possibility is that the sensation could be due to referred pain or sensory connections between different nerves.

As your symptoms indicate, you may be suffering from a migraine or tension headache. But one should not exclude the possibility of serious conditions. I suggest consulting a neurologist for further detailed diagnosis. While you wait, work on reducing your stress and have a good sleep at night. Recall that your health should be considered first and you might need medical attention if the situation requires so.
