Please give me advice on my implants

I had breast reconstruction in 2012 following a mastectomy and then 5 weeks of radiation. I was burned so bad but healed. I had a tissue expander at the time. My problem is my pec muscle is always so tight .. It feels like this hard ball in my chest. I only did about a B cup size under my pec and my pec muscle flexes every time I do movement on my left side. Also have this dip on my left side close to my underarm that is always sore.I am very active with horses and the more I work with them the tighter it gets. Sometimes it pulls hard to the left that I have a very sore spot in my mid sternum. Does anyone have any ideas? I feel like there is a foreign invader there and any doctor I see or bra specialist they all say what amazing work I had. I am a strong person but this pain has been going on for 4.5 years. What should I do? I don't feel like me anymore.
