HTFU!! haha, sorry but had to say it!
I wouldnt worry about taping it up, it may restrict your natural movement and put extra stress on your elbow/shoulder while doing squats etc. Id say its just tightness in your muscles not allowing the joint to move as freeley
You could always start next week on tuesday to give your body an extra day rest, I found this worked for me when my quads were smashed after the first week. The downside is you get less rest the following week but by then you will be getting more used to it
