low back pain and right sided groin pain

  I'm not sure if anyone on this forum can help but I thought I would give it a shot.  Over the past four months I have been having right sided lower back and groinGroin lump
Groin pain
Groin stretch
Jock itch
Swollen lymph nodes in the groin pain.
  The initial syptoms (symptoms) where only this but over the past two months I have had right calf pain in my leg.  My familyBirth control and family planning

Naproxen enteric coated
Naproxen sodium
Naproxen-lansoprazole
Naproxen-pseudoephedrine
Naproxen-sumatriptan thinking it was only
  strained back.  This did not work,  but helped a littleLittle noses decongestant
Little tummys.  After this he prescribed prednisonePrednisone
Prednisone anhydrous,  thinking still it is a strained back.  This helped a littleLittle noses decongestant
Little tummys but the pain was still
  very intense.  He recommended an MRI of the lower back and some therapy.  After one month of traction and excercise we are nowhere and the MRI was negative,  by the way I am only
  31 years old.  He suggested then a physiatrist who did a bone scan and another MRI.  Everything here once again is fine.  I have seen a chiropracter for one month and this has not
  helped.  
  The reason I write you is that all of the doctors don't seem to think I should be having the groin pain I have described to them.  The pain I have in the groin is a very dull pain
  which worsens when lifting and especially sitting.  The testicles are not sensitive but the pain appears to be in the tube connected to the back of the right testicle.  If pressure
  is put on this tube it hurts and will cause groin pain most of the day.  Also,  I must mention it feels as though the groin muscles
  are so tight that I have to stretch them almost every 15 minutes.  It also feels like when the groin muscles are real tight the pain in my "tube" is less then when I stretch my mucsle.
  Overall,  stretching does help the pain a little,  but I have been on pain killer for 4 months on and off and I am unable to active whatsoever,  to the point I cannot even pick up my
  children.  One other point to note is that the pain goes away when I lie on my back but immediately returns when I stand and especially sit.
  Another thing to note is that I was kicked in the testicles very hard in February,  but these symptoms did not seem to come about until May several days after golfing and lifting
  some heavy items.  I have not yet seen a Urologist but am planning a visit next week.  Am I wasting my time at a Urologists or could some trauma to the testicles produce back and leg
  pain that goes away when lying.  Also,  I have NO other symptoms such as blood in the urine problems during sex,  etc.
  Sorry for the long post.
  Thanks you in advance for any suggestions.
