Had a TIA Tue. 8/19, feeling faint yesterday & shortness of breath. Yesterday and today left leg hurts at shin area and unable to put weight on it. Could they be related?

Had a TIA Tuesday now having leg cramps on left side could this be related?

Had a mini stroke earlier in the week, now having pain in left leg could this be related?

Yes, it can be. Best to contact your doctor if you haven't already done so.
