Shift.ms is better if you're logged in

I was diagnosed in 2014 Neurologist felt like I had been having flares for several yrs. He determined from my medical records and MRIs maybe 10-12 yrs. I've recently been moved into a secondary phase of MS. I overworked in the yard about 2 weeks ago and I've been in horrible pain not walking well. I do feel a lot better today. But I just noticed I have a bruise on top of my foot. I have not hit it or dropped anything on it. Can someone help me understand this?
