low back pain. 43 y/o athletic male. Pain - tightness while at ress. - sharp pain when bending beyond 25 degrees - sharp pain when lifting right leg - sharp pain when sitting up from a supine position. -sharp pain when sneezing/coughing History - This area has given me problems since i was 12 years old. I remedied the problem through strength exersices and have been pain free for years having only one other flair up in my mid 30 s which was worse in that i could not even stand up. Today i run about 20 miles / week, and recently added steep hills and incline cross overs to my regiment. Last 4 days - rest, heat, massage chair... no improvement... in fact it feels that it might be getting worse withouth the cardio in my routine. Self diagnosis - stress fracture of sacrum, tendonitis. Wife Diagnosis - alignment... go see a chiropractor (i disagree) Please advise. thanks
