Palpitations and tightness, a side effect of the contrave?

Hello, I want to add some details to my question.

I started contrave on August 5, 2020.

Step 1 went well, no side effects aside from dry mouth.

Step 2 also went well.

Day 1 of Stage 3 (Sunday, August 16), in the afternoon, the situation is spoiling:

-Right side of face going numb

-Sensation of "light" head briefly

-Palpitations (130 bpm at rest)

-Feeling of tightness in chest/throat

I consulted emergency room, given symptoms, to rule out a heart problem. The doctor gives me 2 electrodes to be sure I ask if I usually have panic attacks (no) ... nothing to report, I am sent home.

Symptoms subside in the evening.

In the evening, I take my tablet, nothing to report.

The next morning, I take my 2 tablets, it still makes me feel tight in the chest/throat in the late afternoon... I decide not to take my evening pill. The next day (The 18th) I also skip the morning and evening dose...

The 19th, I start again at step 1, until today.... I still have oppression on/off.

Is this a side effect of the contrave?

Will it (may) get better with time?

I forgot, higher heart rate generally, too.

And sometimes tingling lips

It's not so much a shortness of breath feeling.... But the feeling of tightness, like someone is sitting on my chest.

Can all the symptoms be related to an allergic reaction/intolerance?

Is there anything we can take to mitigate the side effects?

Thank you.

Since I had started back at 1 co. per day, I will "slowly" work my way up to step 3 and then 4.

Hopefully the effects will diminish over time.

Last question, is there a heart rate limit to not exceed, outside of physical activities?

Thank you!

Can numbness/tingling in hands/forearms also be a side effect?

Thank you!

I see my doctor in November, if needed, I will call to move my appointment closer.
