I've been struggling with Achilles tendinitis in my left ankle since I damaged it dancing in 2012. In August 2017 it got very bad and I was off work for 3 weeks, and have not really been normal since. In around October 2017 I damaged my right Achilles when I was cycling to work. Because the left was still not good, I had overworked the right one trying to compensate.
Now both have flared up at once, and I am at a loss for what to try. Last year I tried physiotherapy, but this didn't work out well. The repetitive nature of physio exercises I think really irritates my tendons, and they just kept failing. There is certainly no way I can do the number of reps the physio wants me to be able to do!
The other major problem I keep coming up against, in terms of getting taken seriously - I am not in much pain. When my tendons are starting to fail I feel a sensation of numbness and weakness, usually in one side of the ankle to start with. This gets stronger and stronger until I start limping and ultimately can't walk. If I force myself to walk then I start getting some pain, so obviously I stop forcing myself to do what is hurting me. Maybe I am just stopping activity before most patients would? Anyway, when I went to physios they were confused, because I didn't really feel any pain when they were manipulating and palpating my tendons to diagnose me. They went with a diagnosis of Achilles tendinitis because of the location of the symptoms I do have.
I tried 2 different private physios and an NHS physio. Both private physios thought I should be able to do more than I could (believe me I tried!) - they were pretty keen on loads of heel raises, but I could never get above 10 double raises (both feet). I am sure I re-tore my tendons trying to do all these heel raises, it set me back massively. The NHS physio suggested I start with a Theraband to build up strength. I didn't get to see her again as it was an emergency one-off appointment, but I got the impression she would have gone down the heel raises route as well after a few weeks with the Theraband. None of them thought I had a major problem, as I wasn't in much pain.
I have also tried heel drops in the past, this was a massive mistake and even the physios told me to avoid them.
Currently I am on crutches to try and offload. Over the last 6 months my ankles have fluctuated quite a bit. I had periods when they improved and I started cycling to work again, then something that seems really minor happens, like I wore a smart pair of shoes for a day, or I had to push a bit on my bike to be safe in traffic, and they flare up again. I can't do any exercise or physio at the moment.
I am a 38 year old woman. I am 164 cm tall and about 55 kg. When I'm well my main exercise is cycling to work. I also do ballroom dancing (1 - 2 hours per week, but just as a hobby, not competitively or anything), gardening and walking at the weekends. My doctor says to rest, but I am worried that from how this is dragging on it is more serious. But don't know what chance I have of further investigation on the NHS

Sorry for the long post, I am desperate for help and tried to include lots of detail. I am worried I will never be able to go back to cycling again, as it was the cause of the injury to my right ankle. Any thoughts greatly appreciated!
