16 weeks with Covid and migraines

So I just found out I have Covid and I’m dying from these migraines... it’s almost to the point where I’m going to take excedrine. I’ve been trying to take Tylenol and it doesn’t even take the edge off. I feel like my brain is swelling pushing against my skull... is excedrine really that bad if I’m in this much pain? The only other choice is the ER.
