I have had weakness to my right hand during preganancy to this present day(4 yrs).my hand doesn t have the strength to hold a pen and write smoothly as I used to. Holding the pen between my fingers cause weakness to write . I have too put extra force and strength to do it then it leads to pain in the hand . I am now on Amytriptlline to assist with writing or I would not be able to write with ease. I can only use 25my anything less would not allow me to write . I have done autoimmune blood test. Nerve conduction and MRI of the spine . No results . I write continuously at work. Help please.
