Groin pull not healing...it's been months!!!

I am an active person and have been the last 15 years....I play basketball a lot in the mornings and haven't been able to really play since May. I ended up playing in mid June but the pain was so intense after playing that I stopped after a couple times. I went on vacation for 2 weeks and didn't do anything during this time except walk around. It wasn't too bad at that point and thought I could play. So in early July I tried to play again and the pain returned. That was back in mid July and I haven't really done anything since. 

I ended up going to an orthopedic and he had me first get a back MRI and then subsequently a hip/groin MRI. The conclusions were that there was a strain in the hamstring and groin. I was told to go to physical therapy and it would go away soon. So I went to a physical therapy center here near me. I started in mid August and went for about 4/5 weeks. To make a long story short, the physical therapist had me do a lot of strengthening exercises, like clamshells, adductor holds with bands, some core exercises, isometric hamstring holds...then we progressed into some jumping. They also placed ice on my back and had me lay there for 15 min. I was very frustrated with this process because I was not getting better. I kept going back and they just had me doing the same thing over and over, adding some exercises as we went on. They never touched the muscle or massaged it at all. He just kept saying if you strengthen it it will get better. After the 4th week I bought a book on trigger point therapy (The Trigger Point Therapy Workbook: Your Self-Treatment Guide for Pain Relief (A New Harbinger Self-Help Workbook).  It talked about the micro conractions within the muscle and how massages are required. Tom Brady's new book talked about "pliability" the same concept with deep stroking massages to elongate the muscles. 

I have a foam roller, lacrosse ball, and I began using them on the hamstring and groin..the adductor magnus and brevis I think. I still had pain following a couple weeks. This injury is not going away and it's really frustrating because I love to play sports and do activities and second I need it to de-stress. 

My job involves walking around in the field some and at times climbing a ladder which is not a big deal. I haven't done any cardio since mid July and I still have a significant tug in the hamstring and more so in the groin. It's not going away...

so the next step I took was try acupuncture. I've been going for the last 3 weeks and I'm not sure I'm feeling a significant improvement. I will say that he definitely cares and is trying to solve the problem. He does acupuncture, electrostim in the hamstring and groin, and lastly deep massages that are very aggressive at times. I'm not expecting a miracle but I don't understand why this is not going away. I still feel hip, groin stiffness and pain when I move around.

I read an article on a forum where the original poster was talking about a doctor therapist he went to that did ultrasound therapy and some other stuff. I included his post below for info in italics.
