It's very very likely, GrandmaD. Any too high (or too low temperature for that matter) can have a negative impact on our body. That said, it's only temporary and does not set us back in the healing process. Your body is getting better and better anyway. It's very good you're sharing your WD experience, because it will help all the people visiting the forum understand the reasons (too much of physical exertion, diet, temperature, etc.) behind the temporary worsenings they have.
