Is It Normal To Have Light Headedness After Stent Placement In Heart?

I am a 48 year old female recently diagnosed with PAD. I have had stent placed in my right leg artery that was 99% blocked and just recently November of last year a 99% blockage in my LAD. I ve been reading and discussing with others how they feel/felt after a stent placement and so many have said they don t even know they have one until they think about it. I feel discomfort every day not an I need to take a nitro discomfort although I ve considered it to see if it helps. It feels like someone is gently squeezing my heart, I get random sharp pains that make me stop in my tracks but don t last long. I ve talked numerous times with my cardiologist and he tells me he thinks its muscle related. I ve also noticed for no reason i ll get light headed just for a sec or two. I can be sitting, lying doesn t matter. I m on Plavix, Levoil and Cholesterol medicine. I know after my situation I m more aware of my heart but is it normal to feel this? I have been exercising and so far no pain but I had no symptoms of a possible heart attack lingering either. The only thing that lead us to the heart cath was my leg.
