I am an 18 year old male, and in around the past 6 months I noticed a strange change in my body, and that was muscle weakness. I knew the muscle weakness I was feeling wasn't normal for me.
Generally, I felt fatigue in my LEGS walking uphill and walking upstairs. At first my GP said I strained my legs and prescribed me with neurofen, then after a very long time I felt no improvement and I knew something really wasn't right. So I went back to my GP and he said it might be a vitamin d deficiency. He sent me for a blood test, and then my vitamin d level came back at around 33. Somewhere in the mid 30's anyway. So this isn't particularly high, but not majorly low, and I wasn't convinced that my level was low enough to feel symptoms (since above 30 is considered normal).
I took my GP's word for it, and for months felt no improvement. It is only in around the past few weeks I have felt significantly less fatigue in my legs, but they are still slightly weak. Now I am not sure if my leg weakness is slightly psychological, because I may be thinking about it all too much when I climb stairs, but now I am just scared it is an MS relapse, because I am now convinced I have MS. Also I am not sure if it is because it is winter now that my symptoms calmed down, as MS patients report harsher symptoms in the summer. I seem to also be slightly worse after a hot shower, which once again, links to heat sensitivity, which leads me back to my MS fears.
It is horrible to be a young, fit, 18 year old male, and then I feel like I have the leg strength of a 60 year old. Is it possible that my vitamin d level could've caused me so much problems? Or does it sound more like MS?
If neither, what other things could be causing this? I am not sure if my doctor just thinks that I am making these symptoms up, or he is just always thinking the best case scenario.
I just need a confirmation of what is wrong.
