Weight gain on one side of body and eye twitch.

[Landslide08]

I have gained a good bit of weight over the last few years. (about 60 pounds) I am 32yrs old 5'10 and over the last 6 to 8 months have been favoring my left side of my body. Meaning I can't help but lean on that side alot of the time. My left arm, leg, and breast is noticably larger than the right and I get a twitch in my left eye sometimes. I am animic as I most recently found out and have to take iron everyday. I have noticed that my heart has been beating oddly sometimes, out of no where it would just speed up and beat hard for a few seconds and then slow back down. My legs and ankles swell some after siting for a few hours at work. I also have notice I bruise very easily and they take a very long time to go away. The top part of my shins feel like clay inside (that is the only way I can explain it) I can press down with my finger on it and it will stay like that for a few seconds and it also turns white. I also have some sharp pains in my legs and lower back on occassions usually while sitting at work.
I hope you can tell me what might be going wrong with the left side of my body?? I know I am not a very active person but if I start to become more active like fast pace walking 30 min a day will I have a heart attack?

Thank you for your help.

Sounds like a sort of edema.  That "clay" feeling in your shin is retained water.  This is likely what's affecting your left side and could be related to a lymphatic problem.  You need to see a doctor.
