Sir, I 'm 29 yrs old male. For the last the six months, I 've been suffering weakness in 4th(ring) fingers in both my hands and foots. Due to this, I cant lift weight and do any hard work. I feel weak and have pain if I try to do so. I 've already consulted three doctors including senior resident in Nimhans bangalore(all are among the best in the city). After taking MRA brain, MRI spine, they couldnt find anything wrong. I 'm taking "pregabalin" tablet course for 6 months now. Already 4 months is over, but still I cant find much difference. Could you please advise ?
