Straining Spells

Hi everybody, I have had chrons for about 3 years. Most of the time I have no major pain or problems. Except for having to go to the bathroom a couple of times a day I have been doing pretty well.  I do occasionally have a problem that I did mention to my GI doctor and regular doctor and they both couldnt give me an answer. I am hoping someone here may have experienced this or have heard of someone who had gone through this. It started in April. I would have a bowel movement and it would be long pieces. My legs would get numb and tingly. After the bowel movement I would get a sensation in my ab area kind of like an upset stomach. It would force me to run to the bathroom and it would make me strain to go to the bathroom and not much comes out. This will go on for 3 or 4 times within the hour and then stop. A few days later it does it again and went on for a week. I then didnt go through this until August for a week and then it stopped until this week. So it seems to come every 4 or five months. Something is making me strain to go even though not much comes out after the first bowel movement. My GI doctor gave me some medication for IBS as he thought it sounded more like that as my discomfort seems to come from just above my groin area. The medication was for cramping. The medication really didnt help me and it blurred my vision so my doctor told me to stop. My doctor did a B12 test and potassium test and everything came back fine. I started a new job this week and have been stressed about having to run to the bathroom 4 or 5 times in an hour. Kind of embarrising. So far it has happened while at home so I am keeping my fingers crossed that I can at least make it through the training period without people knowing. It is kind of painfull when I am straining but something is making me go even though I have pretty much emptied. If any body can help or has any advice I would love to hear from you. Thanks.
