If I suggest to you my throat pain did not subside for almost two years, would that help you to understand the battle in which you are still engaged? And if I could add, especially this time of year, there is nothing written in stone which says you cannot have a cold, strep, or sore throat just because you have had cancer. The healing takes time, lots of time. The pain is normal and so very annoying. The days seem endless. Life at times seems dreadful. The plans you make are disappointments. Eating is a constant challenge.
The chemo probably, in my opinion, slowed your ability to heal. Take what nourishment you can, ice cream if it works. How about lemon drops, custard, soup?
This pain will go away. But it may take many months. You are drafted into the cancer recovery army and there isn't much you can do about it until your time served is done.
Two months after 9-11 I ended up having my cancer lump removed and my battle begun. I too was drafted. Two years later I began to feel normal, or what my new normal was to be. The twenty years since then I wouldn't trade for all the world's gold and horses. But I will say that every little issue you will face will make you think that the big C has returned. Fact is you can just get sick like everybody else and that maybe all it is. And it should be noted it wasn't always easy street. The damage done has been a constant battle since day one, much like a wounded vet who learns to function and enjoy life as it is. In fact just 14 months ago I had a surgery to repair cancer damage to my jaw from radiation. But as fun as that was, life goes on. I am doing just fine.
Hang in there. Two steps forward and one step back as we say is still progress. This whole experience will change you and as a general consensus, change you for the better. We cannot hug you and make the pain go away. We cannot carry you to life before cancer. All we can do is encourage you, listen to you, and pray for you.
