I need some insight.

The past two weeks I've gotten lightheaded a few times and I'm not sure why.

I'm currently cruising on 150mg test and have been for a while. Haven't gotten bloods recently but last time everything was fine. Liver values were a little high.

The first time I was at a restaurant with my girlfriend. I had a really bad sinus headache from allergies and half way through my meal I got real lightheaded for 5 or 10 seconds and that was it. Took my blood pressure when I got home and it was elevated 145/85 or so.

Almost a week later I'm in the grocery store and as I'm waking the isles I get this real faint lightheaded feeling for a good 10 minutes as I shop. Nothing serious it just felt a little weird. BP when I got home was 135/75ish

Today I pulled into the gym parking lot I got that same mild lightheaded feeling again right before I went to work out. Today my blood pressure has been lower than usual. 121/75 was the average. My BP is usually high 120s low 130s.

I'm really perplexed about this. My diet isn't on point right now and I'm rehabbing a shoulder injury. But everything else is the same as usual. No medications and blood pressure is okay when I check it.
