I have been having lower pelvic pain on the right periodically for the last couple of days. Yesterday I was pulling weeds in the front yard and was sharp enough that I had to come inside and sit down. TOday I was doing a core workout and I again had the sharp pain in my lower right pelvic area, painful enough that I stopped what I was doing. I haven t had any fevers, nausea or vomiting. I have been more tired over the past couple of weeks.
