This is why I need the sleeve!

I have a very active job and am expected to wear jeans to work for safety reasons. Since we found that I have a blood pressure problem I have been put on medication. Problem is, the medication makes me sweat like a polar bear in the desert. Doesn't matter what I am doing, I sweat for the first few hours after I take it. I found that this weekend at work I developed horrible chafing between my thighs that made it painful to walk by the end of the day. I get all of my hours in 3 days, so this meant I had 2 more days to go like this! I tried powder, but it didn't seem to help. Today, since I was not working (which believe me is a heck of a workout most days) I decided to ride my bike. It was so painful! I am up to a half mile (which is an achievement from where I was two weeks ago) and I completed my ride. However, I am now in so much pain it is hard to walk much less consider working out tomorrow. At the rate this is going, I can clear up the chafing by Friday which is just in time to do it all over again! I'm trying really hard to get into the proper lifestyle and get my exercise daily. I have done it before, and know that I easily get addicted to the endorphins and quickly miss it if I don't work out for a day or two. This time it is really hard. It is already hard trying to get yourself back into shape carrying more than 100 lbs of extra weight (what is that, like a whole backstreet boy I carry on my shoulders every day?). I just don't know how I am supposed to do this when a work out causes excruciating pain. Seems like reinforcement NOT to work out. I just don't know what to do!!! First the skin condition and now this? I feel like I am blocked at every turn towards a healthy lifestyle.
