Muscle aches and tension......HELP !!!!!

So, I've been experiencing some extreme pain in my lower joints/muscles (hip, ankles, thighs and knee's) to the point where I've had to call off work a number of days just to get better.....then I'm hurt all over again the next week with a different part. I've been taking two (2) Tylenol to try and get some relief and that's not really working. I'm also using real ice cubes and hearing pads along with Epsom salt baths......is there anything else I can do to help ?!?!?!? I'm 13 weeks and 5 days with my first child
