Whats wrong with me?

Dont go away yet, this is not a whiney "why me ?" blog of things that have happened/not happned to me.
Its as simple as it sounds.
3 months ago ,It was my Son's first birthday, I had started going to the gym just 2months ago and was feeling pretty good.
I hadnt lost much weight but felt toned and energetic and enjoyed my kickboxing, pilates and abs classes.
All the instructors were good to me, probably because I was the only one who really looked like I needed exercise (This part of the world everyone look like they walked straight out of runway.)and I was a good student asked questions, and really took interest and never quit although I was the last person to finish everything and anything.
It was fun, to come back home and practise the fake kicks on my husband .
The practise always ended while my son enjoying the fake -action and my husband turning a little crimson while twisting my legs or hands while I scremed,more shriller than usual.
I would always wonder "Is he thinking of carrying the same energy to bed", and BAM, he would twist me more like a boy with rage and now its my turn to turn crimson.(With anger ofcourse)
All this came to an end when in of those classes I probably kicked too much dreaming that I was born to do these kickass kicks.
The next day I had trouble running on the treadmill my hip muscles were revotling like they didnt want to be part of this..
My motivational speech of " Imagine yourselves in those itsy itsy "polka dots yellow bikini.."" didnt seem to work either.
I should have taken a clue, but I aint no quitter, so I went again next week and I could hardly run in the kickboxing class..

I went to the friendly instructor(Did I tell you, he had just complimented me that I was doing really good and was gettting stronger.) and asked him "if there was any stretching exercise that I could do in case I had a muscle catch.
He demonstrated a few tricks but suggested that if I am hurt , I probably shouldnt be exercising.(Which seemed like a distant possibility at that time.)
Well, I went to the doctor she promptly asked me to stop exercising for a week and gave some pills.
It did feel bad that I would be missing the kicking classes , I consoled myself that its just going to be week.
To fend my plummetted Spirits I promised that I would try the new GM diet which my husband had just finished previous week.
He claimed he felt great and energized.
So it was monday and it was fruits only day.I ate a plum and something and took the painkiller.
within 10 minutes I was seeing 2 images, my vision was blurred..I called up the doctor and he asked me to stop taking the medications immediately.
With all the insurance changes, numerous lab / doc appointements ,I am still anxiously waiting to get my period9(Used up 8 sticks in w weeks) or pregnancy blood test) results to get the MRI done.
In the mean while I fell down the stairs again,and I was just thanking god that I didnt fall on the same hurt hip.
Guess what , I was wrong.Now starting with the tail bone I have pain ending in the middle back.(My husband jokes that may be my tail is growing back and I am evolving...)
sometimes my other hip(not the orinigal always painful one) starts hurting just to show how important she/it is.
In the mean while I have terrible cramps in stomach and other places which I didnt even know were supposed to engage in giving cramps.
I just went out to get something 2 streets away and my shoulders are hurting now..
Really, whats wrong with me?
