Pain in the side.

I don`t know if it has anything to do with my hypermobility, and ehlers danlos, but since about 3.30 yesterday afternoon I have been in agony!
I started having twinges in my left side, round about the area which would coincide with the bottom of my rib cage. The twinges got more and more frequent, and more and more painful, during the evening and by mid evening I was in agony with sharp stabbing pains every few seconds which made me wince and jump. The area was also very sore and tender to the touch and I could not even bare to have the material of my clothing next to the area so painful was it. The whole of my left side, from breast down to hip, radiating slightly round to the front and back was very very tender, though nothing was showing on my skin, no redness, no rash, no apparent swelling, yet I only needed to touch it and I jumped with pain. I tried to concentrate on the television, though I could not get myself comfortable, and by ten o`clock the tears were streaming down my face even though I attempted to stop them, the pain was just so fierce I could not bare it! When my husband realised how much I was suffering he brought me painkillers and a wheat bag, hoping the heat would help. I was wary about putting the wheat bag near to the tender area and I very carefully placed it as close as I was able, it took about an hour and thankfully the pains began to subside a little, soothed by the heat, or by the pain killing medication, perhaps both I don`t know, I was just glad the pain was a bit better! Eventually I decided I had to try and go to bed, reluctantly as I could not see how I would be able to sleep if the level of pain kept the same and I had to ask my husband to warm up the wheat bag once again. I laid it on the mattress and flattened it out, then carefully lowered myself gingerly on top of it. It took a while but eventually I managed to get a little more comfortable and I did drop off to sleep, though waking a few times in the night with the stabbing pains. I woke early this morning because of the pain and carefully got dressed and I have thought it best to rest today as moving around seems to aggravate it.
I have no idea of the cause but wonder if it has anything to do with my hypermobility and ehlers danlos, as I can move in a certain way and my ribs seem to dig in and hurt me. I have had something similar to this before, but not to this extent, not so long lasting and painful. Hopefully it will right itself, I don`t fancy yet another trip to the doctor!
