From this study (6 days ago):
I do have Relapsing-Remitting MS. Went to doctor the other day I thought the issue in my hips, leg which is occasional in the right hip but pretty constant in the left. It is not painful- but it feels tight- and I have slight problem walking. Also having balance issues. Doctor things the hip is bursitis and not related to the MS. I think it is spasticity.
From this study (2 weeks ago):
I was on Tysabri for 6 months and ended up with breast cancer 2 months after I stopped taking it. Is there a correlation. I heard if you are Brac 1 or Brac 2 positive Tysbri could be the culprit. If anyone has family members that have had cancer, check if you are BRAC positive. It could save your life or at least a horrible ordeal.
From this study (4 months ago):
have been having severe back pain on lower spine right above tail bone

Have you considered seeing a neurologist? Sometimes incontinence can be caused by nerve problems.
