For over 3 weeks I have had excruciating pain throughout my lumbar tailbone left hip and pelvic region on my left side. Pain is permeating down the leg as well with pain in the groin crease. I do have osteo Pena and have Had a sigmoidectomy in 2013 due to colon cancer. Immediately following surgery I developed C diff that lasted for 6 months. I was left mal nourished for about 3 years. I have struggled gaining weight and nutrition. I gained 10 lbs in the last 4 months and weigh 110 lbs. My blood came out good. CT on abdomen was good and X-ray on leg was good. ER Doc said MRI necessary. My primary doesn't want to thinking I have fibromyalgia and/or myofacial pain chronic as usual. This is NOT my usual pain! I seem to get slightly better with rest but I try to move around or do a couple things and I'm right back in bed with excruciating pain. I can hardly stand to bear weight on the hip/buttock/pelvic region (left side) to get up or sit, stand, bend. What could be going on with me? My pain is real and I feel like I'm not being taken seriously my my doctors as I have been going through this in a lesser degree for a few years and dealing with it with no pain medication. I did forget to mention that 2 weeks b4 the cancer was found I had shingles in my left arm and had colon surgery just after the blisters were gone. I also have a chronic constipation issue that developed from having c diff for so long. I have to take a rigerous regimen of miralax and diet because I suffer from dismotility. HELP!
