First of all im sorry your mom is going through this. It's exhausting and frightening. I had Covid April 2022. I was not hospitalized but was quite sick. Lasted about 2 weeks. 6 weeks after Covid I started getting heart palpitations. Later to be known as Long Haul Covid. I am 63. I was watching a movie with my husband at the beginning of my long haul Covid and my heart felt like it was jumping out of my chest. I was light headed. My fingers were tingly. I thought I was having a heart attack. I checked my blood pressure, its was 156/123. I told my husband to bring me to ER immediately. A very long story trying to make short... since then I have been in the hospital 6 times. 4 times admitted to cardiac the other two overnight in ER. I am a competitive tennis player and have never had any health issues. My blood pressure is usually to low. The hospital over the 6 times did echo's, MRI with and without dye, ultasound on my chest neck and legs (to make sure there is not a blood clot) and a CAT scan on my head. The last visit 3 months ago they kept me for 3 nights and did many of these tests again. The results; perfectly healthy heart. It's baffling and again frightening. My side of my face at one time went numb. That warranted another trip to ER by ambulance. That time I thought it was a stroke. Again they found nothing. I was beginning to thing they were incompetent or I was nuts!
The last 2 months I thought I was over long Covid. I have read several things saying it can last up to a year. I have had these issues for a year in April. I believed I was in the clear.
Last week I hired a trainer at a gym 2 days a week so if something were to go wrong they would be right there with me, and I could use their help. I went 1 day doing legs, I was fine. I went again on Friday and did upper body. 20 minutes intro the training I felt lightheadedness as well as my heart started beating rapidly I had chest pain, I stopped immediately, but the issues did not. Since then I am back to where I was with the same health issues. My resting heart rate yesterday was 115. Normally 82, give or take. My heart as I write this is out of control beating rapidly. I have over the past year read many articles from reputable sites on long Covid. They are learning more about this as time goes on. When I first had it I had no idea what was going on with me because it was not talked about publicly because they did not have a name for it. I never had issues with my lungs " thank you God" I do have very sharp pains randomly throughput my body. I had sharp pains in my head that I later learned were ice pick headaches. They are gone. I am writing all of this in your reply hoping to give you some understanding of what some people are experiencing after Covid. Also hopefully somehow it may help others to understand they are not alone. I felt in the beginning I was the only one in the world that had whatever I had because noone understood. The ER nurse had a nerve to say " maybe it's in your head... have you been drinking tonight? I was furious! I have a drink at the MOST once a month, and that is socially. Believe me I really felt alone after that comment.
I hope this helps. 🙏🏻
