Damaged tendon about 2 months ago, could it be permanently damaged?

I damaged my tendons in my upper arms about 2 months ago from excessively working out. It was pretty bad to the point where I was pretty much standing like a hunch back. It was probably the worse pain I've ever felt in my life. My right arm was swolen to almost twice the size of my left. After about a week, it stopped hurting, but it was weak. The most I could do was about 3 pushups (normally about 35, yeah not much) The weeks the followed I sort of used it here and there lifting things and pushing things, so it never really healed fully. That went on for over a month. For the past 3 weeks though, I haven't used it at all in any heavy lifting. But it still feels kind of weak. I could only do about 24 pushups before I can't anymore, and afterwards my right arm feels funny. What could be wrong, and what kind of doctor should I consult for this? I have no insurance and I'm not exactly financially stable so I just want to make sure if I make a trip to the doctors, it's necessary. Thanks
