Based on your symptoms and complaints, you should see a doctors
">doctor, perhaps the same doctor who had treated you previously and can determine if these symptoms are similar to what you had before or if they are new or concerning. Given that it has been a few years and these symptoms are at least partly new (the migraines and the fact that your conservative methods of treating this don't seem to help), I would not feel comfortable recommending any treatment over the Internet without having met you first. While it can be difficult without money to see a doctor, there are times when it might be worth doing, and this appears to be one of those times. Most hospitals and doctors will have a way for those without funds to see a physician, and many cities will have a free clinic with volunteers that can help. From what you have said, it sounds like you have already tried some of the simple remedies for low blood pressure, such as increasing electrolytes and fluid consumption. If these have not worked, blood sugar could be another likely cause. Please speak with a doctor, and work with them to find a way to get the care you need.
