I was going to say too that summer time is not my good parts of the year. Not that the pain or weakness is gone away at any time during the year, but summer time is harder due to the sun for me. and if there is many other things happening to you, it would be easy to self diagnose so that we would at least have an answer of some sort.
Others here are better at responding to you than I would be.
Hope your day is good to you
