I met with an accident in Oct.2000 . The right radial nerve was damaged.And I was prescribed Mazetol 100. After some time Eliwel-10 was added. I had developed lisping and forgetfulness. About 4 years back I consulted another doctor who prescribed Pregaba plus and Euresta 300 SR. Now I have to grope for words and the name of persons or things. I also miss out on dates of important events. The nerve also appears to be shrinking steadily. The pains increase multifold when the sky is overcast. What shall I do to get relief?
