I keep getting mildly sick. I got COVID19 back in Feb 2022. It was followed by a very strong flu. Since then I get a mild flu every other month or so. I will get a mild fever. My head is bald and I get colds very easily. Please, what сan I do about this? Before this I used to get sick maybe once every other year. Now it seems like I'm sick multiple times a year. I am thinking of getting a blood test and seeing what it shows.
