Hi I'm 30 years old. About 6 months ago I found myself struggling one afternoon to hold a potato whilst peeling it. My arm felt tired and stiff and I felt like I needed to shake it out, like you would feel after strenuos exercise. After a few hours it went back to normal. Gradually over the last 6 months this stiff/tired feeling has started affecting my left leg too. At first I noticed it about once every couple of weeks. I wouldn't say my limbs are weak as I can still exert the same pressures as my other arm/leg but they do feel fatigued and achy. Over the last month the frequency has Increased and i notice thi maybe 3 days out of 7, more so in the evenings.

I went to the GP today and he is going to check my B12 levels and thyroid, but he did skim over the possibility of MND. I went in there thinking worst case scenario was MS. Now i'm a bit worried to say the least. Has anyone experienced anything similar? my face, head and right side are unaffected.

Thanks in advance.

Thank you for consulting e-healthforum. Concerns over motorneuron disease and MS are not substantiated in your case. It is primarily due to the fact that your symptoms are transient in nature. If I understood correctly, the stiffness is produced by activity and there is no apparent weakness in the affected limbs. It is hard to be certain without having results of neurological examination, but I would consider dystonia as a cause of your troubles. It would be reasonable to obtain brain and cervical spine MRIs, to be sure, but they are likely to be unrevealing in your case.
