I had something very similar. I’m a 72 year old two time cancer survivor. I started getting headaches after my first chemo. I found that Esgic or Fioricet worked for awhile. Sometimes I would have to take two. I was working as a teacher then while undergoing treatment. But over the years I also had cluster headaches on the left side and taking Topamax at a low level and slowly increasing finally took them away after almost a month of titrating up. More recently I saw a physiatrist who had me do some therapy but also prescribed this regime; take two Aleve in the morning followed by Tylenol four hours later and then two Aleve at night. I had suffered for over two years and this was what finally broke the pain cycle for me. I do have osteoarthritis and it’s significant in my neck. Whenever I start to feel I headache come on I first take fioricet. Most of my exercise is in a pool and I now live in a warm climate which has helped. I’ve tried a tens unit too but relief is minimal and temporary. I recently had a masectomy and have had significant breast and back pain from the surgery. I was getting trigger injections but I found the medication they used started up a migraine type headache on the left frontal quadrant which I have had for three weeks. I won’t get any more. I’m now trying the Alleve/Tylenol regime as nothing else has worked. I even tried Ulbrevy with no luck. At night I’m taking two gabapentin and this is helping me sleep and get some relief also. I’m going to try Gabapentin during the g the day when I don’t have to go anywhere as it makes me sleepy. When I can get Lyrica in Mexico that lasts much longer than Gabapentin but my insurance won’t cover it. I hope some of this might be helpful to you. There is nothing more debilitating than a constant headache and it takes the joy out of living. Good luck!
