recent difficulty in spelling words
hi all.. Recently, i had a problem in which i find difficulty in spelling some letters.. for example, i find difficulty in spelling the 'b', the 'sh', and the 'j'.. This is all recent. the people i'm talking with donot notice me spending a hard time spelling but iam. moreover, i stutter in words containing repeated syllables..for example 'hololulu".. i cant remember words now but u got the idea.. and recently,since only 2days, i feel my tongue making some involuntary movement to the extent that i cant sleep at night. i've not slept the previous 2 nights.. anybody experienced this? please offer me ur help!
