Weird arm and hand sensations

[UtahCaregiver]

My 67 yr old fiancé had hemorrhagic stroke 7 months ago affecting right side. He has continual weird sensations in his right arm and hand that he describes as humming, tingling, numb, sometimes painful. Also his hand will move randomly and he really has to focus on it to reduce that. His hand and arm have regained some function but he struggles with using them.His leg does not have the same sensations. He’s tried gabapentin, bad side effects, now lyrica but it doesn’t help that. Any suggestions or anyone else have similar experience?

Boy, I really feel for your fiance. This is info from the link I will provide. "Problems with pain and sensation—People may experience pain, uncomfortable numbness, or strange sensations after a stroke. These sensations may be due to many factors, including damage to the sensory regions of the brain, stiff joints, spastic muscles, or a disabled limb. An uncommon type of pain resulting from stroke is called central stroke pain or central pain syndrome (CPS). CPS results from damage to an area of the brain called the thalamus, which is involved with sensory perception and movement. The pain is a mixture of sensations, including heat and cold, burning, tingling, numbness, and sharp stabbing and underlying aching pain. It is intense in the area affected by the stroke, such as the face, extremities or trunk on one side, and is made worse by movement and temperature changes, especially cold temperatures."

What kind of rehabilitation therapy does he do? Physical or occupational therapy? He sadly may not get full relief from these post stroke symptoms. I think a good support system including mental health is essential.
