After a backpacking trip this weekend i've developed pain, swelling and redness in my left achilles tendon.
The trip was on Friday and Saturday where about 10 miles up and down hills were hiked at a fairly strenuous pace, it was also the first trip of the year. There was never a popping or sudden onset of pain, but more of a burning that i figured was a blister forming. On Sunday I noticed a rubbing sensation as i would raise and lower my foot, at this point I realized my tendon was probably swelling. By Monday redness had developed and the swelling was getting worse. By now (Wednesday) the 4 inches or so from the base of my heel up my achilles is a dark red bruise. I have been resting it as much as possible and icing it a couple times a day. There does not seem to be a limit in my motion however I have not pushed the limits for obvious reasons. Raising and lowering my foot while sitting does not cause any pain.
Does this sound like a normal case of tendonitis or could this be more serious such as a larger tear or partial rupture? Most of the people that I've talked to about tendonitis (friends and family) have never seen the visible color change that I am experiencing.
Any thoughts or suggestions?
