Serious side effects after vaccination

I got my Pfizer vaccine 1st dose on 26th of July. At about 20 minutes after vaccination, I had muscle cramp on my leg causing me couldn’t walk. From the 1st day until the 3rd day after vaccination, I feel sleepy, dizziness, headache and sore arm at the injection part. However, at the 4th day, I started to have sudden difficulty in breathing and it lasted for few hours then the 5th day, I had difficulty in breathing and sudden chest pain and the symptoms lasted until now. On 4th of August, I went for checking blood oxygen and ECG test. The first ECG test seemed like abnormal but the second one became normal. Although the tests results look normal, but I’m really feeling unwell. Sometimes, I woke up from sleep because sudden heart pain and very difficult to breathe. Am I suitable to take second dose of Pfizer or better don’t take it?
