About 5 months ago, I had an allergic reaction and went to the hospital where they put me on a high dose of prednisone (60 mg for 5 days). After the last dosage ran out, I had quite bad withdrawal symptoms where I felt extremely short of breath, my chest felt really heavy, I had a bad migraine, and I had a hard time getting to sleep. After a couple of weeks, these symptoms started to go away, but it was quite gradual. I discovered that I had become sensitive to caffeine as well where I would have heart palpitations for days after having a cup of coffee, so I cut that out of my diet completely, and they mostly went away. About two months after my allergic reaction, I had a family emergency where my mother was diagnosed with stage four cancer, and suddenly, I was solely in charge of her care and expenses. My symptoms worsened and now my arms and legs would get numb at random. My chest started feeling heavy again as well. I went to the doctor and was told I was probably having a bronchospasm and was told to start taking a daily antihistimine and use an inhaler every 4-6 hours. After about a week, the chest heaviness and shortness of breath went away though the spontaneous numbness was still there. About a month later, the chest tightness came back. I went to the doctor again, and she ran an EKG and ran my vitals and found nothing abnormal. I was told to resume the antihistimine/inhaler process. I went back a month later because of the arm numbness. My at-home blood pressure cuff was telling me that my right arm had a systolic pressure that was 15 units lower than the left arm. When I went to the doctor again, everything was fine--the right one was actually higher. (So perhaps the cuff I have isn't entirely reliable.) I'm still occasionally having symptoms and don't know whether or not to continue to keep going to the doctor. I've started exercising more regularly, and I feel great when I'm doing that. During this time, I had also taken two weekend trips and felt completely normal during the duration of those. When I'm busy, I don't really notice any symptoms. It's worst at night when I'm trying to settle down to go to sleep or anytime when things are a bit quieter. I feel 95% sure that this is probably a manifestation of my anxiety first from the prednisone withdrawal/allergic reaction (which had also occurred during a stressful time with my finals for my Master's degree, followed by graduation) and resurfaced with the stress from my mother's cancer diagnosis. Prior to this, I never had any medical issues at all. I'm 26 years old and in good physical condition. My dad passed away in his mid-50s from congestive heart failure, but he had lived an extremely unhealthy lifestyle (e.g. drinking, overweight, never exercised). No one else in my family has ever had any issues with heart disease or breathing issues. Money is extremely tight right now, so I'm not sure whether to just accept that this is anxiety-related and learn to cope, especially since the symptoms are very slowly easing up or if I should go back to the doctor, so she can run an x-ray. When I last visited her, that had been her suggestion for a potential next step, but she seemed to think it would be extremely unlikely for me to have suddenly developed some sort of heart disease given my lack of family history and lack of any related heart issues as a child. Thoughts on what I ought to do next?
