Good evening I am a 30 year old male and I am 6 1 male and just within the last few days I have expierenced my muscles hurt and they have tighten up...especially on my arms, wrists and calf muscles and it has gotten worse over the last 24 hours.....im taking acetemeniphine and it helps a little bit....but it s horrible in the morning because I m laying all night..however..sleeping is fine and have no problems, but my legs feel like their having Charlie horse state most of the time..I m also having trouble gripping things as the muscles in my arms go into pain as they feel tight and hurt...it feels like when you squeeze you fist and hold it....also the 2 muscles that is connected behind the ears on each side to the collar bone hurts too and feels like they have been over worked....but not a single muscle looks bruised or swollen...I get slightly dizzy but it hasn t happened often but I wasn t concerned about that....it is just the muscle tightness.....I m eating fine and as said before sleeping fine too....I m trying to take care of a 15 month old and working full time....I m not sure what the problem is and would like to see what is going on to make me feel at ease....I m on Vitamin b6 daily and also venlafaxine (taking it for 2 years) and have never had a problem since taking it....I have been carrying my daughter around and moving stuff around at work but cannot recall my tweeking or pulling something but could this be a severe muscle strain that is causing this?
